Boyfriend on Tinder

So I just recently discovered my bf of a little over a year and a half is still on tinder.

When we first began dating, maybe a few weeks in, he got a tinder notification and was so apologetic about it. He told me he used to use it before we started dating, and told me he would delete it immediately. He swore I was the best thing that ever happened to him and hed never do anything to ruin that.

Fast forward about a year, I found that he had messaged a model on Instagram, telling her she was so beautiful and he just had to shoot his shot. Nothing came of it and he felt horrible when I found out. He swore he wouldn't cheat on me and that hed stop messaging girls.

Now this weekend, he left his old phone at home and it was on, and I saw he had an email notification from Tinder that said "thanks for your order". I asked him about it & he said he used to pay for tinder before we started dating, that he deleted the app from his phone but never deleted the app, so it must still be charging his card.

I honestly didnt believe him so I made a fake tinder account. The next morning, we were laying in bed together snuggling (he woke up a few min earlier than I did) when i checked my phone, i saw he matched with my fake account 11 minutes earlier, while I was asleep next to him. I told him my friend matched with him and he said it must be an old match. I told him her account was less than a week old. He then admitted that he "uses tinder to talk to like minded people" we argued for a bit & talked about splitting up. I told him he needed to delete his account and the app, & let me watch him do it, & not to continue going on dating sites. He agreed but he doesn't seem to understand why what he did was wrong, he thinks I am overreacting, that he didnt physically cheat so it is ok.

We live together, I have no family/friends close by and cannot afford to live on my own. I love him more than anything, but I am so incredibly hurt by what hes done. He is a great guy in every other aspect but this. I am so torn I don't know what to do.
