Long one sorry! Lots of history with the ex who is the father of our 11yr old DD. We initially had a very amicable dynamic after our split, with him sharing childcare 50:50, but once his mistress came back on the scene and they got back together, things quickly deteriorated between us.
Communication has been dire for 2-3yrs and been via email only - their choice - and he now only has our DD every other Sunday and Thursdays after school til 7pm. No overnights. He has failed to offer ANY form of maintenance in this time and has never offered to pay for/buy anything for her and I have failed to ask as I don’t enjoy having anything to do with them if I don’t have to. My current DP is our main breadwinner with me working part time and treats my DD like his own. We have a LO together now.
Recently I have grown a pair and decided that it’s about time he started to A) spend more time with his child and have her more regularly including weekends/overnight and B) pay something. The communication broke down due to them, despite my attempts to re-kindle a civil playing field and even tried to go to mediation but he flat out refused on both fronts. Due to the lack of civil communication, I have said that we would be contacting CMS to deal with it. I emphasised that he chose the unpleasantness between us and have never really understood why.
His response has been A) his current lifestyle and work commitments are not conducive to having her more “at the moment but we’re working towards it” and B) he doesn’t see the need to involve an outside agency and has now decided that we should “move forward” with a more amicable approach again. He is keen to “make a financial arrangement that we’re all happy with” All very convenient!
My dilemma: I have stated time and again about wishing to have a better relationship for the sake of our DD and now he’s receptive to this so I feel I should be the bigger person, bury the past and accept. My current DP is STRONGLY against this and feels he’s had his chance to be forthcoming with money and be “nice” and chose not to, until now, when he’s been threatened with CMS and probably doesn’t want them looking into his finances (a longer story!). He feels I’m being a fool for rolling over but I feel I should at least give them a chance and see what he has to offer.
AIBU for not just pursuing the CMS route?
Or
AINBU for taking the chance to keep the peace and have a better relationship for the sake of my sanity and my DD?
Sorry for the long essay and thanks for all opinions!
