Ive been with my partner for 14yrs and we have 3 children together. We have had a great relationship at times but I feel like over the last few years thing have not been great and we are more and more unhappy with each other. We bicker and argue a lot, but he doesn't think we do. We dont have a sex life as I dont want it, but he constantly has little digs at me about sex, how horny he is ect. He will often blame me or the kids for how he is feeling (you are making me angry) and talks to me with very little respect at times, I can't disagree with him and he'll tell me im "always having a go at him for nothing". He had issues with his mental health a few years ago( we also feel he has ADHD) and I feel this is where the relationship broke down. He was becoming very anxious and would be paranoid, accuse me of cheating, check my phone, was angry about me owning a vibrator, would question if the books I was reading had sex scenes in them and question how I new men on my FB friends list ect. I ended up deleting all my FB friends, throwing away my vibrator and lived in a state of constant alert and anxiety about him thinking I was up to no good. He saw the Dr and was put on medication which helped but he still sometimes has these feeling he admits, I also still have trauma from this time in my life and feel on edge around him sometimes. I've often thought of leaving but feel guilty because when we are happy its good and we have a lovely little family, I feel bad for the kids but I also have no money as I don't work and he controls all the finances (other than Child benefits which go into my bank each month and I use this for clothing the kids) I have no friends i can turn to for support and no family. I'm lonely, lost and stuck and dont know what to do.
Any words of support or advise would be very much welcome.
