What should i do?

I think that you should talk to him, not just for 5 minutes before activities but really talk to him about what has been worrying you. If he doesn't want to split then he obviously wants to help you. I think that if he doesn't talk to you alot then he needs a little space, mabey you two might have been spending too much time together. If you really think deep and hard mabey you might need some space too. Also, I know from my boyfriend that they don't really like to text that much. my boyfriend never text me unless he really needs something. If i want to talk to him then i have to go first. About the pregnant thing, congrats! unless this isn't a good thing... then sorry. haha. hope this helps!
