Ugh men!!

He says nothings wrong but he haven’t kissed for 4 days!! We have been together almost 16 yrs we are 29 yrs old with 2 kids and lately just arguing a lot more and the last one was big he got all upset cuz when I brought his dad his mail we got talking and before I knew it I was there an hour so he started texting me “Hello you get lost” and I text back “No still at your dads, was showing him some heater online he asked me to look up for him” then he text me back “ yea sure you are it gets a little suspicious when you are over there for an hour” I asked him what he means by that and he said “ we don’t even talk that long and much when I’m over there” I called bulkshit cuz he was there for 2 hrs just the other day before I went over, so when I got home he just blew up on me calling me ever name in her book bitching at me and trying to say shit about me cheating (No j haven’t!!) but once I bring up about him sexting some chick he just starts going at me cuz he got caught. At this point we sleep in the same bed but no “goodnight Love you” or goodnight kiss we don’t got to bed at the same time either anymore but when we do he turns to the walk right away, we have only had sex 4 times in the last 3 months when I ask him about it he says he just tired and that but that’s his excuse for everything then he gets mad even more when I try to talk to him about our relationship.
