It is all up to the mother, she has the right to give it any last name.
No, if possible your boyfriend (as the father) needs to be involved in bringing up the baby.
Find another boyfriend.
break up
Break up with him now!
Only after your break up with the current boyfriend and only after several months.
Just do it don't be a little wuss. No, do NOT cheat on this person. If you have feelings for another person then DO NOT cheat. You should instead break up with your current boyfriend, it's a lot better than cheating.
It depends.... Why you want to date this other guy. Is it a selfish reason or is your current boyfriend not treating you right or it could be you just like this guy more. Well you can never really tell until after your choice has been made. But make sure if you do break up with your current boyfriend that you won't regret it.
Move on and get over him!
If your friend is working with another girl to try and break you and your boyfriend up, she is not your friend. The best thing to do is make your boyfriend aware of their game and ignore them both.
Break up with him. He isn't worth it.
Time to seek another boy. BREAK UP WITH HIM. EMBARASS HIM.
If you have feelings for your ex, but are in a relationship, i suggest you break up with your current girlfriend/boyfriend, and see if your ex still has feelings....
