Really don't know anymore

Don't know if my bf fell out of love with me or if he's just not the man I thought he was. He asked me to marry him, we've been trying for a baby for 3 months. And now what we have just ends in a matter of 1 day? He doesn't seem to care at all either. This is the hardest thing I've ever gone threw, relationship wise. How can he cum inside me everyday and tell me he wants to be even be grandparents together one day to this. So sick I feel like I'm going to puke. I'm currently on my 2ww and actually hope I'm not pregnant this time around. Gosh love is such a hard thing. I never would've imagined this happening to us.
