Ok..I am a single mommy who is inlove with my ex..

as hes not the father to your son, ( or is he im confused lol) he probably wont want to get back with you tbh, your the one that dumped him, and if he loved you he must have had to go through hell when you left him, and he grieved but now he's moved on and is happy with the way things are. if hes the father of your son then thats a different story, your bound to get back together. however, if you truley care for him, you really should tell him how you feel. hope this helps (: x
