You didn't tell us enough. What was it about that that made you feel sad?
Maybe try not to be around him then, the best you can.
because she thinks your gay
If you just came across them then No. That is the past and he is with you now hence the EX :) but if he is keeping them hidden from you or you catch him staring at them or he becomes mad if you ask him about them then maybe there is a problem. :)
NO
If this man or woman your ex, you can't be upset anymore. If your talking about when the two of you were still couples, yes who wouldn't get upset knowing that your spouse is cheating on you. Now that the two of you is not couples anymore, you can't be upset to what he or she is doing.
Often yes
I would be mad, and upset, and confused.
yeah he is just sad he missed out
Yes, i think he does
Smile, wish him well and go on about your business.
It can be human nature to be upset when your current husband is talking to his ex wife. It is also normal for her to be upset that he is doing things with you that he was not willing to do with her. Talking to your husband about how this situation makes you feel and coming up with a mutual decision regarding the issue can help with this.
Because she's a female.
Most likely unless she really does not like you.
