What would you do if you found your husband on Grindr?

So me and my husband have been married for 3 years and we have one daughter age 1. The last time he was intimate with me was back in December 2018. I have tried to spice things up in the bedroom & nothing seems to be working. One of my friends had told me that I should make fake accounts on gay apps. I thought how silly. I started with making a fake account on tinder/ pof and didn’t find anything. I decided to go on the gay apps as my friend suggested and found my husband on Grindr. I am currently hyperventilating and don’t know what to do... I just found this out today.

Has anyone else found out that they’re husband is gay or bi?

His name on his account was dlclosetguy. I recognized him from a side view and I know his body/ tattoos. He never shows his whole face in the camera.

I messaged him from my catfish profile (purposely found a very attractive picture to put) and he wanted to suck the guys d###. My husband said he’s a cross dresser (which I didn’t know) and he doesn’t do bottom but he’s a top but he’s not interested in sex he just wants to blow a couple of d####. He also told the catfish that he would pay for a hotel. What really confirmed that he was my husband was that he gave the catfish his cell number. I don’t know how long he’s been on this app.. 😢

I’m embarrassed and ashamed. I don’t know wether to divorce him or live this life of lie so that my daughter has both parents.
