Quoting ☮ Phuket:" whats the problem?"
He needs to hear from a guy's perspective that if his girlfriends keep the baby, things will be okay. He needs advice from a mature man about being a father.
I wish you luck OP! If this helps you, I just had my son 3 months ago and when my SO and I first found out (I'm 23 and SO's 24)...my SO wanted an abortion. He was so pissed at me and even though he said he wouldn't leave me either way, it made me doubt what I wanted to do and our relationship. I can tell you it is very scarey on both sides, doesn't matter what age. My parents told me that no one is ever or will be ready to have a baby, it just happens. Trying to conceive later when you're older is usually harder because of stress and makes it hard to get pregnant. That's another chance she takes is risking her not being able to have children at all, and to someone who has already wanted to be a mother it means alot. I was unsure at first but once I made up my mind, he had no choice. I asked him if he really loved me and wanted to be with me forever like he's said, he said yes and I said then I'm keeping this baby. We've had our ups and downs but we made this commitment together to stick it out with each other. He is my best friend, friends aren't worth smurf when you get older and you'll realize that more over the years unless you have some badass awesome friends lol. I'm just saying that you have to take the good with the bad, having a child is hard sometimes but it is so worth it, I promise. You have no idea how much my son has changed not only my SO and myself but everyone else around else. Everyone is so happy having him in their lives, its amazing. I never imagined it would be this great.
One last thing- I also had an abortion when I was 17 with my ex of 5 years and I resented him and my mother for the longest time for making me do it, I had regret, depression, it changed me. BUT I know that if I really didn't want to do it then I wouldn't have. You guys just need to consider each other's feelings and start thinking about the future. You can still have friends, and go out but yes your life will change. Ya never know, you might like who your child makes you become.
