Sigh, I just need a few positive words

Long story short, when my ex and I were together he asked “for time to think” after an argument, to which my friend found him on tinder. I confronted him about it and he said that it was wrong and that he thought we were done & that he didn’t talk to anyone.

We made up, stayed together.

Again, fought and actually broke up this time. I spent a lot of time trying to get him back. Once again, my friend sent me a screen shot of him back on tinder. Totally in his means to do so considering he is now single. But yesterday I asked him if he had moved on or was trying to, he said no. I was trying to fix things, then boom. This. I sent him the screen shot of his tinder profile and he blocked my number and me on Instagram.

Guess I got my answer.

I hate myself for this because I’m 26 and he’s the only guy I have ever trusted. Now I am like fuck...... can I even trust ANYONE? I’m so hurt. I thought he was so genuine and I am in love with him still. I feel so hurt and stupid. I don’t know what to do. I don’t think he meant it when he said he was in love with me. If he moves on this easily? Just....
