How should i approach?

So my husband and i are kinda in a tight patch where we feel like roommates rather then husband and wife. We usually spend our days (once we're home and settle) seperate he's in the living room and im in the bedroom watching tv or whatever. We briefly discuss our days and again part ways. We haven't had any kind of intimacy except a pek on the lips in about 2 weeks. I tried to have sex with him a couple nights again. He didn't want too...so i rolled over and went to bed. The next morning he text he was tired & really sorry that we didnt have sex i responded its fine...you work hard. A couple nights later i think he was in the living room watching porn. I mean why else would you get out of the bed 12 something and its pitch dark. So immediate i felt like he didn't wanna have sex fear of me getting pregnant again and resulted in miscarriage. I also told him were going to have a picnic and watch movies. I order takeout and took a shower. Picnic didnt happen we ate, watch 1 movie on seperate couches. And i got up came in the bedroom to watch tv. I again felt weird and distance. He came and said thought we were watching movies? I replied thought we were done. I just feel so distance from him. Am i over reacting? I also been feeling bored in this marriage & sex life. My husband is so basic routine & so quiet

*No i dont feel he is cheating either*
