Feeling lonely

My husband has been ditching me so much to go hang out with his friends . I can't do much because I'm pregnant and I can't go with him because I'm either too tired or they going to places 21 & up ( I'm 20) plus I'm 7 months pregnant I don't wana go to clubs and bars when I'm 7 months Prego ! . And they all smoke and I can't be around that . He rather leave me home so he can have fun . And when I cry to him to stay with me he complains he hasn't seen this person or that person and I'm boring . What do I do :( . I don't have any friends or family so I'm pretty much all alone
