Being ignored by SO

So im one of those girls who doesnt really care to have attention, but while im pregnant it completely changes. My SO has started giving me less and less attention lately. He has so many other projects for friends and stuff he has been working on, and it keeps him so distracted. When i complain about not spending enough time with him he basically blames it all on our 2 year old taking up his time, which is a massive lie. He just seems to have completely checked out of life at home kind of... not to mention we've had sex like 2 times in the last 3 months (both of which times were initiated by me). I feel so unwanted and unloved right now, but if i bring it up he just pushes it off. 😬😞
