DH and I were together for 10years before we had our daughter. I am not saying we were perfect but we were perfect to each other. Being pregnant did tested us to the limit with the constant sickness,endless health issues and our DD being born with a birth defect ( needed an operation by the time she was 6 months ). But we manage to cope or we thought so...me with an extreme set of routines and him by rebuilding a vintage car and set off for a week throu Europe ( I hated it but accepted as his way of coping) weeks before the operation. Operation was a success and we slowly tried to go back to normal life. Meanwhile I thought relationship with PIL was normal...we saw each other twice a week. Fast forward and DD first birthday arrived!! I decided we needed a day out just as a family of 3 and child friendly. Despite this we did invite PIL a couple of times to join us but in my opinion they excused themselves as it wasn’t what they had in mind ( family gathering with people that never showed interest previously to meet my DD). To my horror a week later my MIL sent a text (she hates phones!!) saying she was fuming she had missed her GD first birthday and she was thinking of cutting thighs with us!! DH was so taken back he couldn’t bring himself to talk to his mum so myself went over and apologised and promised it won’t happens again ( I know!!). Fast forward a couple of months and she Was at it again... this time DD had been sick for a few days, with me getting to the point of complete exaustion due to lack of sleep , and despite being told a couple times no she decided she wanted to take DD for a walk despite her being poorly. What hurt me the most wasn’t the fact she ignored DD being poorly or me being exhausted but the fact she managed to twist the all situation for my DH to take her side and overruled me. Which he did!!! To be honest on that moment I felt our relationship crumble... am I overrreacting when I told him if he can’t support my decisions, like I do with his, regarding DD then our relationship won’t last? ( MIL still thinks she hasn’t done anything wrong and I am being childish)
