Commitment issue?

Elizabeth • ♋Living life, in love.
Does a guy have to come out and directly ask you to be his girlfriend? Hes said many things inferring that im his girl ? Does it sounds like a commitment issue? I have been seeing him for a month or so and we are very much in love on cloud 9 when im with him. He had been engaged 2 years ago and she had a kid with a prior man and said things just didn't work out.
