Yes they can, and telling you that they don't care that your fiance is pregnant is not being disrespectful. It is a simple fact - IRRELEVANT to the lease you signed. You didn't pay the break the lease fee so you "abandoned" the place. Expect to be formally evicted and sued, and you will have less money for the baby, with court costs, penalties, late fees, possibly attorney's fees and interest added to your debt - your obligation throughout the FULL term of your lease. And I'm not being disrespectful either. I'm just telling you the facts - what will happen.
