No rude comments please!

My boyfriend keeps accusing me of talking to someone else. And I literally sit at home with the kids all the time! I don’t go anywhere or do anything unless it’s with him! My phone is unlocked all the time he knows he can pick it up whenever he wants. I have no social media at all besides my <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy apps</a>! I will be 11 weeks tomorrow! So I’m trying not to let this get to me and stress me out to much but it’s like he is completely giving up on our relationship and everything else seems much more important to him and it bothers me so much! I’ve said something to him multiple times and he says I’m working on it and or I will work on it or something! So I’m kinda at a loss here idk what to do.
