My hubby makes friends online; gaming... He has some female friends online & I find myself jealous of them?

b/c he seems to be their friend more than he is mine.I dont mind him playing the game,but w/2 small kids I would never have time to play & join in his "other life".There's even a girl from another state that calls his cell,but he says its nothing but her needing a friend to talk to b/c she is going thru hard times of poverty,having to move & being abused.He is a really nice guy to alot of people,but I don't like the thought of a female talking w/ him on his cell during his work breaks{he wld have nvr mentioned her if I didnt confront him about cell bills & a v/m I listend to where she sd she loved him-he says that she says I love you to everyone b/c shes young & sweet}.I'm not the jealous type at all,but I feel left out.Should I find this a sweet gesture-him helping someone thru hard times or do I have a right to feel hurt?(& I know for a fact he doesnt have time to run off &sleep w/anyone-he's on computer when not @ work) & I also feel mad one would call to confide in married man!
