How should I deal with him

I’m 20 I been with my boyfriend for 6 years on/off pretty much high school everything seem

Great Mother’s Day weekend I was with him because he staying 5 hours away now but we been working out I just found out I’m 5 weeks pregnant but since I been back he hasn’t been wanting to communicate as much saying he just don’t wanna talk but that he misses me I then told him yesterday I was pregnant while we were talking and he was happy but he continued not wanting to communicate but claiming he don’t want to break up I don’t chase especially when I feel unwanted I don’t want to just accuse him of cheating or force him to talk but if I keep giving him this space im scared imma lose interest
