He said he’d pay for abortion then said he lied?

My baby daddy left me while I’m pregnant, he said he would pay for the procedure. We drove for the consult ( it’s a 2 day process) 2 1/2 hours away and they said they’d bill me for $200, now I’m stuck with this bill and he’s all of the sudden saying he lied and won’t pay for it. I feel completely trapped. Can’t i sue him for the money? The lady at the clinic even saw him hand me his card, they just weren’t making me pay on that day when they should have and my appointment for the procedure is Wednesday. We already have a 14 month old and I’m completely trapped
