Pushing him away.

Hello, so my bf and i are pregnant. We've been together a little over a year. our families are super close. Before i got with my bf i was in a not so good situation or "relationship" i had that pregnancy terminated due to complications (3 different drs saw something wrong and couldn't ever hear a heartbeat) it still haunts me because i never felt the love of being pregnant or wanted to be with that person, that was in 2013 . So my bf and i have been together a little over a year, everything feels perfect. Our families are super close and we just hit it off super fast. Hes my best friend who i have told my darkest secrets too. Hes never judged me but tried to help me and pray with me. He doesnt have any kids. Im a single parent to a 7 yr old. My boyfriend (40yrs old) super excited to be having his own. Were about 6 weeks old. He treats me (32 yrs old) beautifully, however now that were pregnant i feel guilty, a bit unworthy to be pregnant again and worst of all i feel like im pushing him away. Im finding excuses to push him away. Even to where i feel unattracted to him. I sooo love him. In general i feel detached from reality and like im losing myself. I hate this feeling.
