Hi.
At this point, I can't really say that I'd trust your ex with you or whether he is worthy of you. If I were your dad, I would most certainly say \"No\" to his getting back together with you at this point.
Please value yourself more. What's more is that you should value your child even more. Your not having chosen abortion is a very good thing but it doesn't stop there. You should now start thinking more about your baby than yourself and that may include choosing for your baby the most suitable father. From what you've written, your ex is not that guy. I'm not saying that he won't improve but right now, he should improve first before he gets another crack at you.
If I read your story correctly, he put you in more physical difficulty because of his playing around. Look, if he didn't tell you about the drugs or the sex he's had aside from you, can you really be sure that what he left you with is not more dangerous than you first thought? What's worse is that whatever it is that you may have now may actually affect your baby. You not only have to concern yourself with your health and your your baby's as regards the pregnancy, now you even have to have yourself checked for his \"gift\".
To make it really short and plain, I know you have feelings for him. You wouldn't have gone to bed with him otherwise. Girls are like that. Boys, however, aren't. We can go to bed with as many girls as there are legs wide open. Please don't be just one of the easy conquests. He knows that you're weak right now and that you'd do anything to keep him.
Make sure that what he wants is you and not the drugs or the free sex. Let him earn his place beside you and beside your child. You and your baby deserve so much better and he better show himself that he's up to it. Otherwise, he's simply not worth it.
You mentioned that you're living with an Amish family now? Listen to them. Many people belittle them because of their beliefs but if there's one thing they are is prayerful and devout. At this point, God might have put you there because you need to listen to Him. Maybe not to become Amish yourself but the environment is undeniably one that lends itself to more prayer and listening to what God wants of you. Please listen.
Take care of yourself, honey. You're beautiful and so is your baby. Let any guy who wants to come close earn his right to be with you.
