love reading

I'm married but also seeing another man (open relationship, everyone knew what they were getting into from the start) I really like this other guy a lot and spending time with him has been the highlight of my week. Recently he told me that he's having trouble dealing with sharing and he's not sure if he can deal with it. I obviously don't want the relationship to end but I'm not going to leave my marriage either. I just want to get a feel for where his head is at and if theres a chance we'll get through this and be able to continue our relationship or if I should just give up..
