First he didn't get you pregnant by himself, you were there and unless he forced himself on you you bare some responsibility for getting pregnant.
Is it right he ran away after you got pregnant? My guy says no but did you discuss having the child, did you take steps to prevent a pregnancy, birth control, condoms? What came from the conversation that you are pregnant and what will you TWO do about it? Was an abortion discussed, was adoption discussed, did you talk about marriage, him giving you money to care for the child etc?
There's a lot there that should have been discussed and how that all worked out impacts whether his leaving is 'wrong' or not. Like if you told him "this is what is happening I don't care what you think" and he left. OR he told you "I'm out you're on your own".
Coming back can be good or bad if he's a jerk, only you can judge if he is or not and if it is better to be on your own or raise a kid with a jerk in the picture through child support/visitation or let him off the hook and cut ties with him for good.
Finally no it isn't wrong to wish he'd just go away, seems like he's a jerk, and if things go wrong with him having any legal rights to his child he can make your life hell. He can prevent you from moving out of state if he has visitation rights, he can make claims you aren't a fit mother, etc.
You need to figure out what is best for you and the child you have with this guy. Wishing him away doesn't solve anything for you.

Obviously it isn't right because if he was mature in the first place, he would still be around no matter if they were together, to make sure the mother of his baby was okay and doing okay. BUT the pregnant mother could wish for anything she wants doesn't mean it'll happen haha, he just sounds like an idiot and unless he was going to do anything for the baby, he can go away and take his sob story and shove it up his arse because he's stating things I already know.
