Please. Help :(

Hi all!

So I'm a British citizen born and my boyfriend is from Afghanistan.. I just found out I'm pregnant and he is currently trying to come here to support me and his child.

He has a 5 year document in Italy and has his afghan passport ( of course )

Is he able to come to the United Kingdom with his 5 year document from Italy? I really just want him here I've been in tears and can't figure out what to do :(

Please someone help me :(
