The father isn't happy.

So I have had 3 miscarriages, all before 20 when I was diagnosed with a heart issue. I was married and we tried for 2 and a half years. (He was my last miscarriage). I was told that with my previous losses and the added stress from the heart and medications that the chances of me getting pregnant were very little. After i separated from my husband I went back on birth control to tame my periods, honestly had given up on the idea of being pregnant. I didn't think it was possible, so I wasn't using condoms. lol you would think with 5 years of infertility and birth control it should be a non issue, but I found out I was pregnant a few days ago. Of course the father is younger and a little immature. I knew he wouldn't be happy but I never expected such a horrible response from him. We have been friends for 6 years, he has seen my struggle and knows that this is a miracle baby for me, but still wants it to be terminated. So now on top of dealing with a high risk pregnancy, I'm facing the stress of dealing with him and raising a baby completely on my own. Even with all of this I am extremely excited and luckily I have an amazing family
