Feeling unincluded, lonely. PLEASE HELP.

So my boyfriend and i have been together almost four years now. We are both 18 and i just found out i’m 8 weeks pregnant. For the past few months He has been hanging out with his friends every single day most of the day. I didn’t say anything at first but now that i found out i’m pregnant i’ve been asking him to cut down on the friend time and try to spend a little more time with me and also come with me to look for jobs. For the past few weeks he’s been hanging out with his friends every single day and we only hang out once a week if that for a few hours before he takes me home so he can go to a friends. He even hangs out with a lot of his friends i don’t like at all More recently he’s been hanging out with some of his friends and their girlfriends and he never asks me if i want to come with and that’s really been bothering me a lot. I know my hormones are through the roof right now but everytime they go on a “double date” and i’m not invited to tag along it makes me cry because i feel so unincluded When i tell him how it makes me feel all he does is tell me u am welcome to come along but i never know what he’s doing until last minute and i don’t drive right now so i don’t have a way to get anywhere. It also doesn’t help that i really have no friends so while he’s out all day/ night i have to sit at home and do practically nothing because i have no one to talk to and no where to go. i just feel so lonely sometimes and it’s just such a terrible feeling.
