Well I guess you need to talk to him, I mean, since you guys love each other, the best thing for both of you will be communication. Talk to him about it, tell him how much the whole situation is bothering you and how sad you feel about it. If he truly loves you, then he’ll try to find a way out and will probably have therapy due to his insecurity. I definitely relate to you ‘cause this is really not peaceful and surely tiring, especially when it comes to relationship, when both of them have to trust each other.
