<human>: Give me a shortened version of the text

I'll make this short. We dated back in 2011 for a year. Brokeup, but stayed in contact over these past four years. I've told her to not talk to me but then time goes by and we become fine with each other again and start talking again. 

The problem is, I still have feelings for this girl. It has been so long now since I've even seen her (2 and a half years now) since she moved to a different state. I would feel like an idiot if I told her "hey we can't talk anymore because I have feelings for you still even though its been forever". I want to just move on but it's hard to not catch feelings for her when she texts me like once a month. She has a boyfriend and they are doing fine, I'm friends with her on facebook and I recently saw they were moving to another city together in a few weeks. What should I do in this situation? any advice?
<bot>: Ex-gf texts me once a month at least. She has a boyfriend and they are doing fine seeing as they are moving in together sometime in the near future.
