Need to vent...

So, I'm currently 31 weeks pregnant, after suffering 5 losses in a year. When my so and I found out things were going well, we were over the moon, now I'm afraid to say things have taken a turn for the worst. I just found out he has been having a "texting" relationship with someone else. I say texting Bc she lives in another country, but she comes here for the summers. Also, last night he went out with his guy friends and a few of my friends saw him all over another woman. I am devastated, and he seems as though he has completely checked out of our relationship. There were no warning signs, no sudden distance between us. Just BAM I'm now no longer his interest and I am all but loosing my mind. I'm so scared to bring our baby into this world, to a broken miserable home. I've tried to get over it... But I can't, and I don't have anyone I trust who won't sit there and judge me to talk to about it. I feel like my world is just shattering.
