Need advice. Husband and I have recently (last 4 months) opened up our marriage (him 50 me 40 - together 17 years, 2 teenage kids) Anyway, he has met a couple women he has a good connection with sexually and has met up with them. I have yet to meet a partner (I think I'm picky and not in a rush unless it the right guy)

We share everything eith regards to meeting up, who they are ect and because of our location he had to travel to meet said women so it's happened only once with both. My concern is that he tells me they are talking everyday, including phone calls where the women disclose their personal plight and issues or just because they want to chat. I'm having feelings about this as my husband has said this is just sex with these women, and in no way a relationship but he also wants to build a friendship. But calling to talk about your broken truck or your kids seems more than just a sexual relationship. Part of the endless discussions we've have leading up to all this was about meeting other people. just to explore sexually. We have enough friends, we aren't looking to expand out network. It's purely sex. I realize that it should be my husband communicating this to these women, but maybe I am being unrealistic that developing a friendship alongside a sexual relationship is equally important. I guess it's the 1st jealousy creeping in. My husband is very loving and happy and in npw way has his time wavered from our family but when we are out of a family gathering which his "friend" knew about and she calls him makes me think maybe she's hoping for more than just a sexual partner... Am I crazy? What's your experience with how much building a friendship can be beneficial or detrimental?
