Confused. please help:( relationship problem?

I'd say leave it a few days, and try to get some help for your ocd. The reason your jealos is that we all get jealous, other girls are slutty and out to grab the man you want, but if you feel it is because you have OCD go and see a specialist, and they can give you strategies. As for the calling him back, its difficult if you go either way. If you ring him soon, he might not be ready and if you call him after a few weeks, he might have given up on you, so you'll have to ask someone elses advice on that one
