Should i keep my baby?

I am 21 and training to be a hairdresser! I'm 10 weeks pregnant! My dilemma is that me and my boyfriend split before christmas and I began seeing someone else! I slept with my ex once in the new year and I fell pregnant! He is 28 and at first was a bit dubious although saying he would support me whatever decision I made! He has now changed his mind and would like me to keep it! However he certainly wouldn't be angry if I decided not to! I believe a lot of his decision is because he has just moved 2 hours away from me and thinks it would bring us back together! Which no doubt it would! The boy I've been seeing these past 4 months has just told me how much he likes me and would be completely gutted if I kept it and moved away as he wants me in his future! I really like him too and would miss him like crazy! My ex and me however only broke up because we never saw each other not because we didn't love each other which makes it harder as I definately after 2 and a half years of being together still care for him immensely! But I suppose more as a friend than anything else! I have never believed in abortion!! And don't know if I could go through with it and I know if I kept it my ex would be an amazing father and I would be treated like a princess and have a lovely life! But then would I regret leaving the new guy who could be the love of my life as he already means the world to me! I know there would be regrets with both decisions! My head is going crazyyyyy please help!!!!! Oh and p.s. I lost my mum 5 years ago and my dad isn't supportive so I have no direct family to help me!
