Don't know what decision to make

Today I took a pregnancy test and found out I was pregnant again. I was a week away from my appointment to get paragaurd and my son is just 3 months old. The father is my ex which is the father of my first son. I'm just so confused about how I let this happen again and let him back into my life after he's been such a douchebag. I don't see how I'm going to even keep the baby because I'm in no position to have another child financially or emotionally. BD told me that if I didn't keep this baby then me and my son would never see him again. He is promising to be there but he promised that when I was pregnant with my son and has yet to come through. I feel like if I abort then my son has no chance of having a dad because BD will never forgive me for that. I'm just so confused and depressed and I just can't believe I failed big time like this and got pregnant by the same loser who has not done anything for my son and doesn't even care about him. Part of me thinks maybe the new baby will make him change and then the next part thinks there is no way possible for me to be able to have another child. I just need advice and yes I know its stupid of me to have slept with him unprotected. I thought since I was breastfeeding then I had a low chance of getting pregnant and we used the pull out method. I have so many decisions to make.

If he isn't there for one baby, he won't be there for another.

If he wants to see his son he will see him regardless of the decision you make. He's just spewing empty threats to try and control you. They always use the child as a pawn to get what they want but you do whats right for you and I would also suggest getting a custody agreement so he cant do anything stupid.

Any man who used my child as a pawn in his games would not be welcomed anyhow. I would honestly abort. And, to be frank, my daughters are 13 months apart, and it was smurfing hard and trying.

Personal experience says, he wasn't there for the first he won't be there for the second. Sure, people change.

You have to make this decision based solely on what's best for you and your son.

You have to do whats best for you and your little boy.

If the father is shady now, he will be shady later. Don't keep the baby because thats what he wants (if its not what you want too).

Make the best decison for you, not him.
You and your little one of course!

That's tough but you'll get through this. Consider all your options! It might even help to talk things out with a friend or family member if you can.
