So 6 years ago we got together in a very random and fast way. My partner (now fiancee) cheated few times during first few months before exclusive. We worked through and she was got pregnant and we both agreed although there could be a few other biological dad's that I would be the babs dad without question or anything.
So move on from this we discussed her inability to be faithful in previous or clearly current relationships and that actually that was ok within our dynamic (not here to get abuse about this part). Anyhow...
What I need advice on is
I know she's not getting anything elsewhere (even though I'm happy to encourage and she knows it's ok). But during last two years sex has become less and less frequent. Even down to having any relief from her being now 4-5 weeks apart. She moans and argues if I use porn and I have never been a cheat so that's out of question. My main thing being when I bring this up I'm an arsehole and insensitive, if I try and instigate get the cold shoulder......
I'm happy to have a modern/free thinking open relationship but just feel ignored constantly and on tipping point of whether it's worth it or not.
Is there something I'm missing or haven't asked. She knows how open and happy to discuss stuff I am just just hit brick wall. Just feel life is too short to keep hoping things change and hate feeling guilty for wanting some form of sexual intimacy and being rejected....don't think women genuinely understand how damaging regular rejection is in a relationship.
Any advice would be very appreciated....
Hoping I'm missing a key thing with my partner...
