SUBREDDIT: r/relationships
TITLE: Me [21 M] dated with my ex [20 F] for 2 years, have been broken up for about a year and a half now, still talk time to time but I want her back.
POST: Her and I started dating before my senior/her junior year in high school. I went to college in a different state for my first year and a half and I broke up with her when I was home over break halfway into my freshman because the long distance thing wasn't gonna work for us and I thought it was for the better.

When I came home that summer we started hanging out, going out to dinner, and having sex just like before. I never wanted to make things official again because I would just be leaving for school again in a few months. I continue this with her til the day I left for school. A few weeks of little contact when I'm at school and she texts me to tell me that she has a new boyfriend and that she is sorry. I was really mad about it at first and thought it was wrong of her, but then again I never put strings on anything when I came home that summer.

Now to the present. A year and a half into college (last Spring) I transferred to a university much closer to my home therefore much closer to her. We have hung out once since then (last Fall maybe), I took her to dinner and we just chatted and hung out with my dog (he's much better with the ladies than I am). When she was leaving my house I kissed her and she didn't pull but I could tell there was nothing to it (if that makes sense). She told me some lines about how she is too busy with school/work/etc etc etc to be dating anyone and brought up things that I mistreated her when I left for school, old issues.

We still talk now time to time, mostly casual stuff about work and school. She is open to making plans though, but assures me her schedule is really busy. What is my best plan of action to make her fall for me again or should I just be done with it?
TL;DR: 
Dated a girl for 2 years. Broke up because I moved away to college. I transferred to a school closer to home (for unrelated reasons). We are both single again. I want her back.
