Most Helpful Guy
Do both just don't take him back. You two don't seem compatable and he shouldn't have to feel like he needs to lie to you. Though I will say sometimes guys stay friends with an ex because they were good friends before hand and ey both realized that they're better off as friends. I don't know the deal with hism and his ex but if you're not comfortable with it and you've talked about it and he lied about stopping then I don't think it'd work out between you two. Plus if you talked about things and he lied it could be foreshadowing your future if you continue to date him. There are other guys who would probably fit better with you.
