So I was with this girl for a while and then we broke up. Because we are both in the same class at university we got on top of each other after the breakup and had a few arguments. It did not end well and I haven't talk to her since last year even though we are in the same class. It's pretty awkward.
I would now like to to apologize to her for some of the things I said. I did act like an idiot at times and can see how I have upset her. I would also like to apologize to clear the air a bit and so I can get on in life.
Problem is it was a while ago since these various incidents. I don't want her to look at it than anything else other than an apology like I'm an ex whose trying to get back with her. I feel as if it could open up a can of worms. Also she is with someone else now and she seems happy so I think she may prefer it if I wasn't in the picture at all even if its an apology.
I do still have some feelings for her but looking logically at the situation and our relationship I think if it was better all left behind. I feel like there is some unfinished business with however it is my gut feeling. I think that apologizing would be the right thing to do as it would provide some sort of ending and I can finally move on. I don't want to get sucked back into it again though.
Any advice?





yeh thats what I'm afraid of it flaring up again. Thing is when I say I have not anything to lose I mean it. I'm quite tired of the horrid atmosphere I walk into when I go into class and she's there. Its pretty awkward even a year after she won't even say hello to me. All I get is dagger looks. I've tried to be civil, not like start a conversation just be polite, but she doesnt want to play ball. I don't even think I've done much wrong in fairness it could have been far worse and it was 6 of one and half a dozen of the other. It's quite embarrasing among my classmates. I'm just trying to be grown up and clear the air and I'm willing to swallow my pride to do it.
