Women, what would you do?

well many of you might know me from my excessive posting about my ex, but my x girlfriend and i of 2 years broke up after a few fights we got in, and she moved on and started seeing one of my friends. Now she says shes happy with him but everyone els tells me they arnt happy. The reason why they fight is because even though he tells her not to contact me ( and threatens me not to contact her) she still does anyway. Thing is im getting my license back 2morow and i was gonna offer her a ride to school on my way to work, and i was just wondering what would be good conversation to bring up? i don't really wanna bring up anything about the past, or her and her new boyfriend, i just want to show her a good time, so maybe she reconsiders dating me again
