It sounds like things are fine with your girlfriend (which is most important), and I figured it probably wouldn't hurt your relationship with her. If anything, it's a great boost of pre-selection that your ex desperately wants you back!
As far as your RA, it sounds like he got caught up in a situation where he had to intervene because you weren't there. I would say nothing really needs to be done between you two because it sounds like a situation that (hopefully) shouldn't happen again. So unless you two encounter each other a lot and there have been other issues you've been having, I would probably not confront him about anything or act any differently around him.
Besides those two, it sounds like you do need to take some action with your ex-girlfriend, however. I'm not sure how your break-up went down, but it might be worth having a conversation with her and letting her know that she can't come by your place like that unannounced anymore. Here are some of things you should probably include in your conversation:
- You'll always be her friend
- It was a great relationship and you're glad you had it
- You'd be selfish to let her know that she can stop by any time when you can't give her what she wants or needs
You might even want to dump some blame on yourself to soften the emotional blow to her. At this point, you already know what you want (and it's your current girlfriend), so it can help to try to show her that you are NOT what she wants (so she doesn't go home crying herself to sleep every night). So you can tell her, "look, I'm nowhere near settling down with
any girl right now. Stable, long-term relationships or marriage are something that is not in the cards for me. There are men out there that feel differently about that, and they can give you what you want and what you need. I hope you understand."
Then from there, you need to cut contact with her (at least in the sense that you aren't contacting her for anything). Your original mistake was probably not making the break-up between you and your ex-girlfriend finalized enough, otherwise she wouldn't be trying to win you back so soon. If she has any hope that your break-up was not final, then that's what'll usually cause her to try to win you back.
This would be my recommendation. After it's done, you can probably mention to your girlfriend that you had a talk with your ex to let her know things are over between the two of you. And you can also mention letting you know right away if your ex begins to contact or harass her in any way.
