F/A issue and I need help

[dizzy]

I am new to this board, but boy do I feel like I relate to many of you. My husband is the flight department manager for a small company. They have 2 jets and a crew of 4 pilots plus a F/A. In the past 10 years, my husband has never had a F/A. But, I am really jealous of this woman who my husband spends a great deal of time with. Just this past weekend the crew went to Kauai for 4 days. His copilot flew his wife out there so my husband was with the F/A during the entire trip. They spent a day driving around the south part of the island, stopping to watch surfers on the beach. The next day they toured the north part of the island, stopped and got a bottle of wine, and then rented a kayak. Needless to say I was very upset. About 90% of our fights over the past 9 months have revolved around the time my husband spends with the F/A. I have resolved to be ok with group time, but my husband continues to do things that are one-on-one with this woman. I have become an insanely jealous person, wanting to know where he is, what he is doing, and always asking why he needs to spend alone time with her. I feel like I am in a corner that I can't get out of. I have asked my husband to not spend alone time with her, but he feels like that is an impossible task because that would mean she would be alone most of the trips in her room, and he feels sorry for her. I need some advice, my 17 year marriage is falling apart and I need some help from anyone that has been in a similar situation.
