I need advice on something.. I'm 17 and 20 weeks pregnant. The baby's father was a family friend I've known and it was a one time thing. When I told him I was pregnant he basically said he wanted nothing to do with the baby but his parents are still being supportive. So I have had this certain guy I have been talking to on and off again for the past 3 years. He recently just re entered my life again. This time something was different. We both agreed we felt more mature to possibly try talking again. Him and I have been through so much together that we both can honestly say we love one another through the good and bad times. He accepted that I was pregnant and it didn't bother him. I did warn him about it not being his child and he didn't have any responsibility at all that we were just normal boyfriend and girlfriend. He had been coming over for the past 2 weeks and we had a discussion about the baby and we both turn 18 soon and he said stayed even though it wasn't his baby he would marry me any day. Well just yesterday a friend of mine stopped by while he was here. My pregnancy came up and she basically told him the same things that I have been telling him. Well when she was telling him I saw his attitude change. After I dropped him off he just texted me saying he didn't know now. All day today we have been texting about it and he just doesn't know what he wants. I understand this must be a lot to take in for him but it hurts me that I trusted him that things would be different this time. I just want advice on what's the next move I should make for myself because I love this guy a lot but this is all very heartbreaking and confusing to me.
