Im 23 and he's 39 if it helps. I had a miscarriage 3 weeks ago at 12 weeks had to have a d and c. I'm severly depressed. The guy I've been with for a year and talked about marriage with ...well I found out he's already married...we broke up obviously....he's texting and calling and I'm not responding...but last night he texted sayin he was tryin to check on me but I'm not answerin so he guesses I'm mad at him then at 10 well good night....what does he want from me?? I honestly fell for him and I thought he had real feelings for me but he's married for christs sake! So please any insight as to what he wants
