so me and my boyfriend have been together for almost 2 years and he still needs to get a divorce from his "wife" before he wants to get engaged. But we havnt spent more then 24 hrs appart from each other since we got together. the last 5 month have been so hard I had my son at 24 weeks and he is 5 months now my due date was December 18 and my son is going into surgery Tuesday to get a trach they tried it before but he didnt tolerate it. but my husband hates hospital and he dont like staying in r sons room for more then a couple of hours and that bugs me because i feel like a bad parent for leaving and not stay long. grrrrr what should I do
