Should i just stop talking to my ex-girlfriend? or should i try again?

So we split up a few months ago- well more so she left me for a lesbian and... Well... we were staying away from eachother- she recently came back saying how she liked me and called me her only Figure in her life that was beneficial to her- I helped her alot through depression and everything else- we were together for four years... and the day she told me she loved her lesbian friend more than me really hurt- Shes a kind and polite girl, Really beautiful- i love her... but- i dont know anymore. Me and her companion were on good terms- now i hate her... but deep down i still love this girl, Even though she mistreated me alot... What should i do? She doesnt outright do harmful things or attempts toh urt me- the thing is she Naive and really believes alot... i made her a promise i'd always look after her- but when she hurt me... i'm not sure- i love her deep down and still yearn for her- what should i do?

Your duty to uphold that promise ended when she left you. She called you 'her only figure in her life that was beneficial to her' it seems she likes you because she gets something out of you. It's unfair to say she loves someone else and keep you hanging on like that. Better for you to move on I think.

Anyone who leaves you for someone else and crushes your feelings in such a way isn't deserving of you anymore. Trust me, I just went through the same thing. Get rid of her, because all you are at this point is free emotional support. And, I know it doesn't feel like things are going to get better, but you're going to be a lot happier after you've moved on. It just takes time.

I agree with everyone else, it won't be easy and it may take time to get over her, depending on what you do, but it would be better if you just move on

More to the point, bouncing off what Codename4711 just said, she isn't the one who needs emotional support right now. She left you for someone else, so they can support her. You need to focus on your own emotional support right now!

I agree she either needs to pick her lover or risk loosing both and not every promise can be kept tell her that u feel emotionally hurt and u need to leave before it gets worse

@MickKito - Why is she suddenly seeking you out? Is her new relationship on the rocks? You maybe being used. Do not sleep with her for now whatever you do. You are young and not a bad looking guy, you will meet plenty of great and interesting girls trust me. First loves feel very intense and can seem a mystery why people go through such crap. It gets easier with time and the right attitude. Like Manga_bird said write this one off and move on with life and find your own happiness IMHO. It is a bitter pill to take at first but better than the alternative. It is not healthy to live in the clutches of a psychic vampire. You are not responsible for her happiness, she is. Now there are 2 issues I see. First the fact she left you for a lesbian, while painful to the ego, should not be taken too personally or as an attack on your sexuality. When people awaken sexually they have to figure shit out and that takes a little time and experimentation so you have to give a half-mulligan sometimes in regards to orientations now days. Secondly, if she went about this in a really shitty way, be rightfully disappointed in her disregard for your feelings after looking after hers. It sounds like while she is not consciously mean, subconsciously she is very selfish due to whatever issues are on her newsstand. I don't know the whole situation so I am broadly generalizing based on experiences and how you described her. If you want to keep such a person as a SO you must own her ass like a pet and attentively lead her or she will likely roam/be lured away again and again. That may be what she really wants and needs, a dominant figure to keep her on a stable path. There are men and women who fit under this category, I am not being sexist. Just the way some people are wired.

I understand what i must do... It's going to be hard; she's all i've known and wanted these past 4 years... but thanks guys- wish me luck...

They're ex's for a reason. My advice: GTFO Look! I didn't have to go into a 700 word essay to tell you that.
