should I leave or ask him to choose?

My husband and went for Christmas in Maryland. I know he ex lives there. So, I told him not to try to find her because that will hurt my feelings. When we returned, I found out she got a gift from him. I asked him if he saw her and he denied saying he gave it to one of her family members to give it to her. I do not bliv it. He keeps telling me that he hates the fact that I do not trust him. How can I?

I hate to be lied to and feel like I should just be like am single.

I am so hurt because I told him not to do such things, but he still went ahead and gave her a gift and my guts tell me he handed it himself

No kid is involved
