Have posted before about elements of this but never in one go for anonymity (hence the name change!).
I left my DH a few years ago as I fell in love with someone else. There was nothing wrong with my DH (good man, solid relationship, mostly supportive and understanding) and we had DD (then 4) together. I just couldn't see myself with him forever with these strong feelings for someone else so I left and in due course began a relationship with now DP. There was no overlap or affair, just had amazing chemistry with him and I had a feeling like nothing else I'd experienced.
XH obviously took this badly but we muddle along now sharing custody of DD and are good friends, so much so we occasionally get mistaken for H&W still as we attend mutual social events and keep each other company. He disapproves of my relationship with DP but is supportive of me as his DD's mother.
I still feel incredibly guilty about leaving. He's doing fine though and DD has adjusted well to us being apart - in fact, she gets the best of us both now due to the new setup - so it's a heart rather than a head thing, my feelings about it.
So new DP and I have had a rocky relationship due to many reasons - we both have pasts with traumatic events, both have young DDs, both have issues with MH at times and have had very little support from friends and family (together and individually) as people don't 'approve' of me leaving XH for him and assume we'd been having a LT affair.
We split last autumn but have been working on getting back together for about 5 months now as I found out I was pregnant. I love him so much and he makes me very happy when it's just us but the difficulty is, due to our current separate lives as parents, both in high pressure jobs and with his family disapproving of our relationship and his DD very uncertain of me as she's used to it just being the two of them, it's just so hard to be together and not be in state of anxiety or worry about something. It's one thing after another being thrown at us.
I just want it to be easier for us both. When we get the odd day or evening just us, we're both so happy with each other. The rest of the time it just feels like no one wants us to be happy. Everything is a struggle and it makes me feel more guilty for leaving a comfortable relationship for one that's tumultuous due to external pressures.
Any advice for me? It's not meaning to sound like a sob story and I realise in some ways I am very lucky but it's such a tiring relationship. Not because of DP but getting our relationship to fit into the wider world!
