Husband has tinder app 💔

This isn't really TTC related but I thought I would ask here and see if anyone has gone through something similar. We've been TTC for 8 years with one loss in 2017. When my husband was scrolling through his phone a few weeks ago I noticed he had tinder downloaded. I thought that was weird but didn't say anything. So the next time he wasn't near his phone I checked the app but there was nothing on it so I forgot about it. This week though when he was showing me something on his phone I noticed the app wasn't there anymore. So I checked his phone sneakily again and found out he still had the app but it was hidden in a folder now and there were a couple conversations with girls, where he was saying they were beautiful and out of his league and wondering why they swiped right on him, and describing what he looks like. I've checked it a few times since then but nothing new has been done on it. I checked his email account while on his phone and saw an email from tinder saying his subscription had expired a week ago and another email saying a previous subscription had ended in November 2018. Now I'm even more worried because a subscription means he was paying for it right? That seems much more intentional and worrisome than just a free app downloaded. What would you guys do? I hate feeling like a paranoid, stalker wife, but we've been together 12 years and I've never felt like I've had to worry about this before. What should I do!?
