So my ex and I broke up after a 2 year long relationship. Short story we loved eachother very much but we were very different people and got into a lot of arguments. i think she saw that i was getting frustrated because the communication was not at the level i thought we should be at (my fault i feel, should have been more patient). I was beginning to become more frustrated and unhappy because i felt like i was sacrificing so much in the relationship. I assume this type of energy would make her unhappy as well. I had suggested couple therapy or going by other things, but they weren’t taken up. I felt she was the one for me though, i just thought it could have been fixed through some level communication. FF - a week before her bday she lets me know she’s unhappy (2nd time she let me know and we had worked on it prior). tells me she still love me but doesn’t know what to do. She decides we should break up after a very sad talk. I agree, but i’m not really wanting it. By advice of my friends i’ve deleted her off everything but i’m deeply regretting it for the past month we’ve been broken up. I think time apart would let as heal but i don’t think i would like to get together again if there happens to be things in between (as a very jealous type - hopefully not over bearing). I’m seeking closure from this but i can’t find it. I’m doubting myself a lot. wondering if i was just a bad BF, and if so, was the things she said to me just a lie. I’ve been trying to cope by going out more, but it’s tough. I do still love her, but not sure what i should be doing. Thoughts? Thanks for reading btw if you’re here TL;DR - GF was sad and we break up because of frustrations. I’m not happy about it.
