Need relationship advice

Good morning ladies... Happy Wednesday!!!

I need help with my relationship. We r about to celebrate our 2 yr anniversary and it doesn't feel exciting anymore. We r both 36 we both have kids from our previous relationships. He works in San Jose and he comes down to L.A. (where i live) he comes down for a week out of the month. Its just that I feel like hes doing somthing. I have gone thru his phone ( dont judge or be rude please) and i have seen that he goes on Craigslist to the personal adds. I have asked him why.. If all he is looking for is porn, there r porn sites for that but why Craigslist and adds from girls that r close to home in L.A. i did see that he texted one of the adds. I kinda consider that cheating he said its not. There have been so many problems between us. I feel he has been the major reason my family and I aren't close anymore cause of the way he is. His attitude and so judgement. He always thinks people dont like him or talking shit about him. He has PTSD and he uses that excuse for everything.. Moving on to the SEX part lol: he doesnt do anything to get me wet. Literally!!! Our sex life is so boring. Now his thing that turns him on is ass, so even tho i think i dont have an ass lol. I try my best to turn him on.. My thing is boobs, if a guy plays with my boobs and starts to touch them i will get extremely turned on. Ask me when was the last time my man touched my boobs?? Go ahead ask?? I cant remember when, its been months. He doesnt do anything to turn me on. Sex for him is. Sleep, wake up around 1am cause he is hard, he will rub my butt for a few mins and then he will pull my underwear down and stick his dick in me.

What is wrong with that sentence?? He did nothing to turn me on, not even touch my kitty to see if Iam wet. I dont think the feels we had before r still there. I think he is done and hes just with me cause he has nowhere to go. I think Iam done with him but idk how to go about it... There r more issues but if i mention then this post will be longer... If u got to this point and have any advice please shoot it thru... Sorry for this long ass post..
