is this normal.

My husband and I have been married for 2 years &4 months . We are expecting our first child together. I will be 6 months pregnant tomorrow. Lately my husband hasn't really touched me or held me like he used to. All he does is just come in the room lay next me and play Xbox or go on his phone. I asked him today what he would like to do and we ended up staying home doing nothing... we don't even kiss or hold hands much anymore.. is this normal ? Is it because I'm pregnant ? Does everyone who's married go through the sanme thing? I already tried talking to him and that doesn't work... I love him so much😞
