I didn't really know where to post this

So a few days ago I found out the father of my child is actually married and never filed for divorce (despite telling me he had been divorced for a year when we met) he just one day decided he was unhappy with his wife and moved out while she was at work and never looked back and started telling people they were divorced so here I am 18 days before I'm due finding out I'm having a baby by a married man and I didn't even know and this is a man that has asked my mom for my hand in marriage and we even had a wedding date of Labor Day 2017 before he left me stating he had an epiphany that he need to take care of his 3 kids and do better for himself without a woman. the wife also never said they were still married but now suddenly she is revealing that they are married and claiming she didn't realize I didn't know and I'm like you showed up at my house, exchanged phone numbers with me (they also share a child so she exchanged numbers so we could communicate about pick up and drop off times) and still never thought to say something about still being married to him... I've already spent the whole pregnancy alone because at three weeks pregnant he moved out while I was at work and told me get an abortion or be a single mom so now I feel like I'm in the twilight zone and I just wanna wake up. This whole pregnancy I've been trying my hardest to block out everything negative and enjoy every moment of it because I refused to be depressed and pregnant over his decisions to abandon me I have had so much thrown at me and still I choose to smile and be happy despite it all. There was a time I thought using glow would provide a positive support group that I could lean on in spite of the drama in my life but between being trolled on here by a mom to be who keeps calling me a fat whore for having a bigger baby bump than hers and just reading some of these moms nasty comments on other posts it's all been more crazy than supportive. I can't wait til my daughter is born so her little face can erase all the drama that's unfolded over the last 9 months. Praying things will get better 🙏🏾
