I have two daughters. Their dad was my second love but first grown up relationship in my early 20s. I didn't want things to end but he ended it because we were arguing a lot. Anyway, we co-parented from when they were very young and he's a great dad. It took me a long time to be "over it" but I accepted and stuck to only talking about the kids and what was needed. He eventually got into a long term relationship.
During covid times me and the ex started talking about more than just the girls. We would text a lot about everyday things, our interests we used to bond over, families etc. we basically had an emotional affair. Eventually those messages turned sexual at times. I was single through all this, he was in his relationship but they were drifting apart. Nothing physical happened for over a year, then we started secretly meeting up. We would go on the odd night out and have a dance, hug, hold hands, went for a meal.
After a few of these meetups we ended up kissing. He felt terrible about it although he had to admit he didn't love his partner in the way that he should, so he told her everything and they broke up. I know what I did was wrong. My part in it is wrong. I really hoped we could be together properly as a family eventually. We continued meeting up and going on dates. We kept it from the girls for a few months, but eventually our oldest DD figured out what was happening and asked if we are back together. I told her we were working on it and we hope to be. She was excited.
Turns out ex has turned into a massive committment phobe as he's got older (he admits himself) and he ended up saying he's not sure it will work between us. I was gutted and felt so messed around. I let him go because I didn't want to beg anymore like I did during the first breakup. I had to tell DD we werent going to be back together. She was upset but did really well with accepting it.
Well lately she has been asking questions and mentioning how she missed her dad's old house and her "step mum" She's 14 now and has put 2 and 2 together and knows I'm the reason they broke up and that we were cheating. I've been honest with her and her sister. She's upset with her dad too but I feel like I'm taking most of the blame here. DD11 is fine and doesn't care about it all. I have a new partner of 1 1/2 years who they both really like, but of course she's disappointed mum and dad isn't together. I've apologised and told them both I'm sorry for the way things happened but it's still affecting her.
She said the worst thing about it all is not only we didn't end up together, but also he threw away his ex. And I totally understand her view, but they were already growing apart and might not have stayed together despite me. I even told him after we kissed not to leave her just for me and to make sure it's what he really wants. Anyway what can I do to make things better? Their dad isn't with anyone (at least not officially, very possibly casually,) I'm now in a happy relationship and I barely communicate with ex. If I do it's strictly about DDs.
Again I know I was wrong and really messed up but DD wasn't even supposed to find out until things were more certain. I can apologise until I'm blue in the face but I can't do much practically and she's happy about my partner, so I wish we could move onto the future as a family.
