My dp cheated on me pre dc. We had been together 10 years when it happened. I was gutted and loved him so much I gave him another chance. 7 years later we have two dc, I love them so much. He is a rubbish father, and that with the past cheating has killed my love for him. My children are young, 2 and 5. I feel bad to leave over something that happened pre dc. I think if he was a good father I may still love him but he is so lazy with the dc he hardly spends any time with them. I feel so lonely and depressed :(
