My Boyfriend Has Tinder...

Ok y’all I need help. Idk what to do. My boyfriend recently lost all his friends. They all stabbed him in the back. He’s always had depression and it just made it worst. Well Sunday night I woke up and went to see if I needed to plug his phone in and realized he had two messages from tinder. I woke him up and we talked. He said he’s trying to make friends bc he doesn’t know how so he made a tinder account to try to make friends.

I’m hurt. We’ve been together for 3 years and idk what to think. I trust he’s not cheating but if he wasn’t hiding anything he shouldn’t have hid it.

Opinions?

Suggestions?

UPDATE

I told him I need space to figure out if I can trust him and he got psisy. He slept over at some girls house the night after this post. And was there with 3 other girls and no guys last night. Then got upset when I told him I was bugged. So I dumped him. I’m so pissed at all this. I was ready to marry this guy.....
