Yes you should confront him but wait and follow everything he’s doing. Get enough proof of facts before filing. I’d recommend a private investigator before hiring a useless attorney.

Personally I’m going through a divorce after 32 years of marriage. I filled due to the fact my husband was on porn sights looking at and talking to various men one that he’s now with that he met on that porn sight and supposedly plans to marry. I had no idea I’ve been married to a gay man over 3 decades.
Family law is the worst cabal of organized criminal legal system in this country. Separated now almost 6 years and still not divorced.
