Our marriage feels like falling apart

I have been married for 1 year and 8 months and i am 6 months pregnant. Recently, my marriage feels like it's falling apart. My husband and I have little to no communication at all, we get on each other's nerves all the time and he seems annoyed most of the time. It is understood that we still love eachother very much and we are both very happy for the baby that we are about to have. But as far as a couple, I feel like we are not one. He recently admitted to me that he finds both of my best friends very attractive and he also admitted to me that he wouldn't mind having a threesome with one or both of them. I know that he is a guy and that's what guys think about, but it still hurt me so much to hear that. Now everytime that we have sex and he is touching me I picture him touching one of my friends and i wonder if he is thinking about one of my friends when we are having sex. He just seems like this completely different person, I feel like I'm living with a stranger. He tells me he loves me all the time and he's always buying me stuff and taking me out to eat and stuff, but yet I still feel so distant from him. I guess my question is this normal? He used to do so many little things for me when we were first dating, little things to show me how much he cared. but now, it's like he thinks he has to do things to show me he cares, he tries to hard. I don't want him to try or think or feel like he has to do things, I want him to want to do things for me. Is it ok that my husband possibly fantasizes about my friends and sleeping with them? Is my marriage in trouble?

Everybody fantasizes, but it was stupid of your husband to tell you. Your marriage is not falling apart. It is natural for a woman to be sensitive when she is pregnant. Your husband is showing all the time that he loves you. Tell him how much you appreciate what he is doing for you. Ask him for more if you feel the need for it.

Go to family therapy, if nothing else helps.
