Hi I’m in the same situation, was with my ex short of 11 years, we brought a house together 7 years  ago, absolutely transformed the place, I found it very difficult but I decided to call it a few months ago, due to a lack of respect for me had a wondering eye, never physically cheated as far as I’m aware!  But was never there for me, never wanted to talk to me he was always on his phone or PlayStation or Xbox, I had doubts about our relationship for at least a year or two, I did talk to him about this, he tried to change but it still wasn’t enough, he just tried to buy me instead of actually listening and being there for me, just a week or two before me moving back to my mums a guy I had met 9 years at my workplace got in touch, this I was very surprised about because we had not spoken in so many years, as far as I knew he had a child and probably was married but turns out he wasn’t married, but did have a child, he went to explain how he always wanted to be with me from the moment he seen me but because I was in a relationship at the time, did not say anything, we started to chat more more then when I moved back to my mums I thought why not, so I went to meet this guy, I do see him very regularly, he is absolutely lovely, so caring, a great dad, between us there is so much passion something I have never had before with anyone else, he literally said he would do absolutely anything for me, always says if we ever end up together he’s won the lottery, he’s also said before getting with his ex and having a child he wanted me first and it’s always been me, but I just wasn’t available, now since being at my mums, my ex has now realised where he has gone wrong and wants to have another go at making it work, I really love him as a person, he’s been in my life so long, but now I’m a predicament that I don’t know what to do, even when me and my ex got together never felt that good as apposed to now how the new guy makes me feel, he hasn’t brought me out yet of the house, my ex I wanted to marry him for so long but he didn’t at the time apparently wanted to make it special (10 years though 🙄) just felt so drained by hinting all the time, I’m quite traditional in the sense I wanted him to do it, but  I’m not sure he will ever change his ways, it’s really sad because my ex I didn’t want it to come to This because I truly at one point loved him so much I wanted to spend the rest of my life with him, but now this new guy has made me feel so special I really don’t know anymore,  because I don’t enjoy stringing two people on it’s not fair because they both say they love me, I feel like the new guy it’s such a risk because I could risk losing everything I’ve ever worked for but if I end it with new guy and things don’t change with my ex I will always wonder, please can I have some advice or similar situations

I really don’t take any pleasure from potentially hurting someone’s feelings but I’m stuck between a rock and a hard place at the minute , thank you in advance and thanks for taking the time to read this
