Early

My boyfriend an I have been together so far for a month . I’m 24 he’s 41 we have a great connection and he is amazing . I have 3 kids and he has 1 . We just found out a week ago that I’m pregnant. We decided to keep the baby , but sometimes when I bring up my symptoms and how I’m feeling he doesn’t know how to be there . His son is 14 so it’s been a while since my boyfriend has went through this idk how to get him more involved or maybe he’s still in shock ..... am I thinking too deep into it ?
