It doesn’t really matter so much if wife’s “experiments” are with a male or female - that’s not monogamous behavior. Unless you both had agreed to an “open relationship” then I suggest seeing a divorce attorney. You are being used as meal ticket - That plus the infidelity will very likely destroy any semblance of a marriage you had. Your best move now is to salvage what you can of your situation - And that starts with an attorney. The first consultation is usually free. By the way - Talk to an attorney first before making or announcing your decision. Know what the probable outcomes are first. Different states have different rules and guidelines. And finally if you decide to get divorced, I recommend using an arbitrator if possible and over “dueling attorneys” in court. The courtroom is the absolute worst place to resolve how to divide up property, parental rights, and financial responsibilities. Yes divorce is expensive if you are a man and you have children. But being bled dry by a parasite who does not care about your feelings isn’t without cost either.

I'm honestly surprised this doesn't happen more often. I mean you leave a person alone with no responsibilities and boundless time, on a long enough timeline this was always going to happen.

You actually allow her to leave the kitchen with shoes? Well that's a deserve it.

Your wife may be bisexual unless there's something you're not telling us. Has she cut you off altogether? If not, you can't accuse her of being a lesbian. A drunken parasite, maybe...

have you asked to join in?
