My ex/child father said I love you girl and I'm sorry?

Basically I broke up with him because we have a child together and he's failed for over a year to help me with our child... meaning. chance after chance he failed and hasn't been there at all to support me with me much so I left... what do he mean because I really don't want to ask him... my response was ok I forgive you... didn't say I love you back
