Need advice about pelvic inflammatory disease. should i ask the guy to help pay for my treatment?

Medical First: You need to be treated for pelvic inflammatory disease before anything else if you have not already. You do not want to be left with active infection and the possibility for long term complications while deciding on who should contribute money. Once treated, sit down and decide if you think you will get financial help or simply argue. Ultimately, the decision will remain in your hands.
