He said you were bitchy, be pleasant and happy when you talk to him. He said he felt like a dog with it's tail between it's legs. What made him feel that way (bitchy, controlling?) when you talk to him, don't try telling him what to do and how, let him live his life. easier said than done, i know!
Here's what could happen. If you keep trying to show and tell him all the things that are and could be different if he'd only given you the chance, he's going to wonder what's the point. even now, all you do is nag at him about leaving (him wanting to be happy) -OR- you give him space and time. keep conversations short and sweet. he's going to start wondering (not tomorrow or next week, but eventually) what changes you've made and why you are acting differently. he'll start calling to see what you are doing (not to control you like now) or just to talk.
wouldn't you rather him come back because he has a new found interest in you than because he's feeling pressured by you to give the M another go. The later reason for coming back will cause resentment in him and not lead to a good place.
YOU CAN DO IT!! i'll keep telling you every time i post because i know you can!
