It is not him you attracted . It is the "thought/feeling" of him. The karmic relationship,the being drawn to each other thought as you stated in your comment. You have liked those feelings and those are still associated with the physical him. It might be difficult to fathom but look back with gratitude for what you have learned .
Feel the gratitude from the good times.Don't be so doubtful of you intuitions
It sounds like you have taken many steps forward from the man and there was a little back pull after the New Years call. Consider this, you know what you want more precisely now. Put your focus on that. Some relations we have with people are just a fine tuning for us, to help us have people in our live that we can interact harmoniously with.
As far as being friends I would complete the sentence " I don't want to be friends and I don't want to be enemies either . Animosity is a heavy burden to carry around. Better to have a neutral feeling about him. Thus not creating any desire, albeit positive or negative.

P.S. Cool nic

That seems like a logical presumption, I agree. Your good feeling attracted the ability of the closures that you needed.

But the thing is that even though you attracted those closures with him you wasn't yet ready (strong enough to see it through) as he was being dominating again, you were getting sucked back in.

This is kind of like revisiting an old pit (you had fell into once) to close it up, so you never fall in again. Even though you are there to close it up, there is still the danger of falling back into the pit.

It seems that this person knows how to "push your buttons".

Your question:

"Was I supposed to allow him back into my life?"

might be better asked as:

"Do I want to allow him back into my life?"

Often people who want power over others will try to make the other person feel guilty & "small" for not doing or being what they are "supposed" to do or be.

The "rules" about doing what you're "supposed to" are imposed on you by the process of socialization, & are only as valid for you as you choose to allow them to be.

If you are living in the flow of the Tao - universal consciousness & using LOA, you will be (& do) what you are in your highest potential in every present moment.

Even the smallest doubt can take you out of the flow, & cause you to feel contracted & constrained by outer circumstances, events & people. Sometimes these doubts & fears may be subconscious, however they can still bring into your life circumstances, events & people which you do not want & which cause you pain &/or distress in some way.

If you hold an intent to be your highest self in the (ever) present moment, noticing thoughts & fears & letting them go rather than holding onto them, they will begin to "dissolve" & stop coming all on their own.

Just remember to bring your awareness & focus back to your intention, when these distractions come "knocking".

You could spend your whole life trying to rationalize, understand & forgive these doubts & fears & they would still keep coming to you since that is what you focus on.

Some believe that the LOA is intended to help people to better be able to be in alignment with their highest potential - the person they truly are. By focusing on this truth of who you are, you will be more able to be this truth in the moment.

As Wayne Dyer would say;

What this guy thinks of you is none of your business.

You need to live your version of your life, & not someone else's.

I would forget about all of these deeper questions for now, since they are making you second guess yourself, making you over-think the situation and making you uneasy. The deeper meanings of this relationship and the why's of it, may not come to you until much later when you have the gift of perspective. It is much easier to look back on things way later and see it clearly than it is to see it when it is in front of you and causing chaotic feelings.

Since it will be hard to avoid this person (mutual friends, same classes, same college campus and etc) just make peace with it for now, is my opinion. If you continue to feel stress about it, it will affect all of you life. Let it go. Be friends but don't let him get too close, or better yet, be aquaintances. Don't talk it over with your friends, don't seek their opinions of him, don't seek him out nor avoid him. As someone else mentioned, just be neutral and don't dwell on it for now. The main thing is that you feel better and move forward. At a later time, you will know the hows and whys of it, and can examine it then from a better place.

@oceansize something as made you go with him. you seam to avoid that.could it be that you are not totaly honest also? as for you trying to make him avoid you going so far as stopping him from going to the same class or stopping him from seing people that you know also.might be going a little bit to far onless the other people do not want to see him also. but that is their choice and not your choice.why are you taking this responsability on you? you say:He has a reputation of lying to other people as well.according to who? who is making that gossip? is that person telling the truth?or is that person having is own interest making this person look bad? you say:I'm obviously still hurt, but what was upsetting me was he was presenting this "let's make peace" as if he was doing me a favor. so you do not want peace you prefer conflict?what is stopping you from making peace?is it something outside of you or is it you?it as much a favor for him that it is for you,or maybe you see it as him taking something from you or your social group and are afraid that other will accept him more if you make peace? are you responsible of their choice?or do you fell that people in your social group are not responsible enuff?
