Actually hoping IABU
Ds's father is a wonderful man and a brilliant father. We are great friends and could spend every day together and never get sick of each other.
When we split it was reasons beyond our control and other things getting the best of us. However for a long time before we split out romantic life was not great. I used to put it down to ds, pregnancy etc but actually I do really enjoy sex I think the spark was just missing with us. It feels awkward when we kiss and I struggle to get into sex and even more to climax.
This feeling is on my side, he enjoys it but men are wired differently and not the complex creatures we are 
If its not there it's never going to be is it?
