Me and my ex split up a couple of days ago. I as the one who initiated it because I felt a lack of romance, effort and interest. I also don’t know if I really trust him. He has cheated in the past on previous partners, and in nearly all of his relationships he has been disloyal in some way. In his last relationship he downloaded tinder just to have casual conversations with other girls because he was bored. We’ve also had some similar issues in our relationships where he’s broken my trust. He has never cheated, but I don’t know if I trust him. He’s been too friendly with a female colleague to the point that he deleted their texts to hide them from me. I’ve also caught him staring at other girls a couple times. He denied both of them, downplayed it like I was just overreacting. I broke up with him because of him staring at other girls, alongside some other issues that never seemed to change. I do really want him to be my person, but I don’t know if there’s any way i’d feel comfortable or safe considering this. He always says that he’d never cheat on me because he doesn’t want anyone else and that he doesn’t want me to doubt how much he loves me. But it’s hard when I don’t do the same and it makes me feel unwanted. He promises that he’ll change everything and be the man that I need him to be, and I don’t doubt that he can change, I’m just scared that his lustful eyes will turn into something worse and i’ll be left alone by a cheating man yet again.
