We have been dating for just over a year and in that time he has been more than passionate. He is always wanting to cuddle and touch me, in the begining we used to have sex daily but as of now it has been more than a month. I have asked him if anything has been going on and he says no, that everything is fine. He has also recently stopped coming to bed when I do, instead he stays up until 2 am and frequently falls asleep on the couch. This is causing a major strain in our relationship and I don't know what to do. Please help!
