Husband Cheating?

"Dear Housewife,

Hi, I think my case is a little complicated.

We married 5 years ago and there was one emotional affair which we talked about it and have solved ( as I think).
We recently immigrated to Australia and my husband repeatedly says that he likes to have sex with Asian women ( no one in particular) should I take this as an alarm?

I feel I lost my self esteem here and am not attractive to anyone while I see women are interested in him. I actually think if he cheats on me I can not fire back and should continue with him anyway and this makes me sick. Any advice?"
