Sorry for long post... Any advice appreciated please.
DP and I have been together for almost 5 years now, have a house together and discussed marriage etc. We get on well, no major arguments, but lack intimacy and haven't dtd for around 4.5 years...!
We had a great sex life when we started dating until DP had a brief breakdown and was diagnosed with anxiety. He was on medication for just over a year which caused impotence and that side of things has never recovered. GP said it's a side effect of medication and will come back in time. I did my best to be patient and understanding in the beginning but I just can't take it anymore! I never considered myself to have a high sex drive but I've gone without for so long and recently I seem to want it more and more.
I have tried to speak to DP about this but he gets embarrassed and defensive and refuses to get into any sort of discussion about how we can move on. I don't want to break up but I feel like we're just friends who live together and I don't know how much longer I can carry on like this.
There was one incident a year ago where he admitted to sending inappropriate messages to a woman at work with whom I knew he had a flirty relationship before we got together. I was absolutely devastated as he has not even slightly flirted with me in such a long time. This did have a huge effect on my trust in him but we managed to get through. What can I do?
