I hope I can get some advice here, I'm beating myself up that by opening the floodgates of this topic with my partner I'll be the reason my son will be part of a broken home.
When I told my partner I was unexpectedly pregnant in 2020 he became very withdrawn. Eventually he told me that 2 years prior he had cheated on me while on holiday- a holiday romance. At that time in the relationship we were not very stable, teetering on the edge of breaking up. So when he told me, I decided to forgive him- not just because of when it happened, but because I was unexpectedly pregnant and terrified of doing it alone.
A year on and in the full swing of parenthood I'm unable to forgive him. I can't give him the affection he needs, I wince when he kisses me or wants to cuddle and sex is absolutely not an option. I can see how much this hurts him and I've put my inability to give any of this to him down to the cheating. I often stay at my mum's when she is going to look after our lo when I'm working, and every time my partner asks if I'm staying there on days I'm not working, my head goes to "well, he must want me out the house for a fling". I've even come home and looked in the bins for evidence I've become so convinced.
None of this is healthy, I know that, but confessing the above to my partner will inevitably open a can of worms that will surely end with us co-parenting. I guess what I'm looking for with this thread is advice on how to navigate this best. Neither of us out happy for different reasons, but we love our family time and I want to keep that going. My son is honestly the happiest little chap and I can't bare to think that if we leave this too late when he can remember it that he'll lose this joy to a broken home.
