WHAT DO I DO

Soooo my ex and I broke up bout 2 months ago because he said he needed a break, not even a week later he had another girl but they aren’t together anymore and he’s talking to me again wanting me to go see him all the time, I still live at home and asked my parents to go see him thinking maybe it could work but they don’t really want him around again... he had very little respect towards my family when we were together, but I’ve been talking to this new guy and things are going okay and now I’m just so mixed up so what do I do?
