I think my friend is inlove with my husband

First I would find out if anything is going on between them. I think most of the time men cheat with someone close to the family. And in your case if your friend is coming over all the time and he sees her everyday he might have feelings for her too. And if you have doubts go with those feelings..I don't think your husband will leave you for being jelous. But if something definitly is going on then I would tell her to get out and if push comes to shove leave him to!

If your gut is telling you something is up, then chances are she likes him and you should talk to her before something happens.

Yes you should ask her and your husband.

I don't know how to make of this. It's a very difficult situation. I guess you confront her to let her know beforehand that you are very aware of the situation. Maybe that will make her on her toes.

why do you suspect her? if she is really your friend nothing will happen either way. do you trust your husband? i think trust is the issue here not who loves who if your friend is in love with you husband thats fair enough - it happens, people develop feelings when in close circles like you,your husband and your friend. but if he loves you any advances by anyone will not succeed and if she is your friend she will respct you and NOT act on any feelings she may have. hope that helps
