im sorry that you feel badly. You shouldnt be embarassed to pm merika, she cares about you.
My friend has a bf who has the same flirty personality that your bf does, and she hates it, she puts up with it but it starts a lot of fights. I highly doubt he will ever change, so if you can put up with it stay, if you cant, maybe you are wasting your time, and putting yourself through lots of stress.
