My significant other was unfaithful for over a year and a half with a female co-worker before I found out. There were multiple days over the next 9 months. The last was June 2017 after which he left his job and we participated in EMS Online. I have found no suspicious activity since then and things are continuing to improve. He now is asking to take a surfing trip out of the country later this month with an old male friend leaving me with the kids. I am resentful that he would ask this after only 6 months. I feel torn, if I say no then he is discouraged about our progress and may feel that I can never get over this. My anxiety has just recently improved, if I let him go it may resume. What is a good solution?
