What do you do if you lived with someone for long time and thought you were committed found out he's been with someone else whole time
Everyone is assuming it's guy. Though the askers username is quite misleading. Angel. Kent.
Pack his stuff and throw him to the curb!
Break up with him!!!
dumb him/her and find someone better
Put him out and find someone who deserves you!
Thank him he did u a favor(not a good guy)!
Dump. You'll never ever trust him.
