Feel so alone going through this

Hi, I am new to reddit but made an account because I really need help/support and don’t feel ready to tell anyone in my “real” life about this yet because of how their opinion of my husband and our relationship will change likely forever….So I just found out my husband has been using OnlyFans and several other similar platforms behind my back for most of our relationship. He has had in depth sexual conversations, sent and received countless videos with dozens of sex workers for as far as I can tell. I know everyone’s opinions might differ about this, but to me this feels like emotional and financial infidelity. We’ve been together for years, but have been married for only 3 months so far. :(

I feel so naive because I know everyone says this, but I truly thought we had the most loving and beautiful partnership and felt so lucky. He is literally the kindest person I know, so loved by my family and friends, and I am just profoundly shocked. So basically yesterday I found out that in just the short time we’ve been married he has already spent nearly $2000 on onlyfans, and when confronted admitted it is probably close to $6000 total this last year. The financial infidelity component is super hurtful because I have been working so hard at my job (that honestly I hate but pays well) to support us and help him out with his student loan payments but he was sneaking some of this money for onlyfans instead…. He even hid a $1000 check he apparently got from his grandma for our wedding gift (I didn’t even know she gave us anything) and spent it on onlyfans.

I literally feel so lost and don’t know what to do and have never felt this betrayed and heartbroken. :( how do you come back from this? Do you tell the people in your lives or try to handle privately? It’s only been a day so I’m having a hard time even considering ending things but I’m sure that’s what some will suggest too. This might be one of the worst days of my life. :(
