Hardly a sex life but he masturbates all the time

So i am just at a loss at this point and want some outside perspective. My fiance and i used to havr a wonderful exciting sex life. Now i woulf say the last two years this has been going on where we hardly have a sex life at all anf.i would say 98 percent of the time i initiate and get rejected so often that i stop initiating and then it doesnt happen. And NO it is not lo libido because that man has a hard on neraly evrry morning and i constantly catch (wrong.word maybe) him jerking off. Like every day every other day or even two times a day. And YES i have talked to.him about it and desperately tried to.communicate with him on it and either be told "we have a sex life" or "i dont jerk off all the time" or just kind of get dismissed on it. I havr desperately tried to just let it go as an insecurity. Then last night he crawled into bed doesnt even touch me because he cant "snuggle and sleep at the same time". Gets up in the morning gets in the shower and i go in to brush my teeath after i get kids up and low and behold he is jerking off. It put me over the edge. He realized i had walked in on him opens the door and says "are you okay?" I said "AGAIN! no i am absolutley not okay" and walked out. Well then he goes off to work and i send a text along the lines of "i dont even know how to communicate about this anymore but i still hope you have a good day" i have yet to get a response. . . . . Am i overreacting and making a big deal out of nothing?
