I'm currently 17 and around 2 months pregnant. The father is also 17. He and I are not talking and he has blocked both my phone number and social media after an argument we had a couple of weeks ago. Immature, I know, but I don't currently have any way of contacting him and he's made it fairly clear that he wants it this way. We really don't get on and have been on and off and almost constantly arguing for around 3 years now, he's immature and also extremely unreliable, since I've known him he's constantly let me down, said he'd do things, be places, etc.. and never followed through and as well as this I have recently found out that he had a girlfriend at the same time as we were seeing each other. He has also been in a lot of trouble over the past year due to fighting and drugs.
As far as I know, legally I don't have to tell him but I'm more asking morally. I originally thought it was an obvious choice not to tell him but everyone around me is telling me that this would be wrong, leading me to doubt my actual intentions and now I'm not unsure whether I believe that this would actually be best for my child or if it would actually just be better for me.
We don't have any of the same friends so unless I was to tell him it's unlikely he'd find out.
I don't know if anyone can really give me advice as I can't really give every single detail but honestly, I'm just looking for some unbiased input.
