I love you, but I can't forgive you

I am 21 years old. I’ve been dating a guy for a year now (April 26 was just a year ago). We celebrated the anniversary in the best way possible, we had fun, danced, and naturally drank.

When we went home no longer so sober, mythe guy knelt down on the street and started saying how much he loves me and that I’m perfectgirl for him. That I never blow his mind, unlike his ex (by the way, in my opinion, she still interferes with our relationship). Shehis sister's friend , and often comes to our house. He was on his knees saying that he was ready to protect me, even if he had to die, as long as I was alive, etc. At some point, tears flowed down his cheeks, and I myself ended up crying, that night he shouted to the whole street that he loved me. I believed, and I still believe... But a couple of days later I found out that while we were in a relationship (in October, we quarreled very strongly and almost broke up) he test-antibiotic.com cheated on me. He was with a girl I knew about, she showed sympathy for him, wrote to him, they saw each other again, because she was a friend of his sister. So, I stayed at home alone for a couple of days and decided to look at photos of us together, but I found completely different photos than I expected - they were naked, smiling. “He cheated on me,” I thought. I didn’t believe my eyes, he always swore to me that nothing could happen to them, and that it was just flirting withstupid girl.

He returned home and, of course, I decided to find out everything. In the end it turned out that they had, after all,sex . He explained it all by the fact that we seemed to have broken up, and that he treated her like a girl of easy virtue. It was very painful for me, such a contrast between the fact that he swears his love to me, said that I am the best and then this. Of course, after those quarrels of ours, a lot of water has passed under the bridge, we went to St. Petersburg, lived there together, and even now test-antibiotic.com I almost live with him. I told him that I forgave him, but I can’t get it out of my head. If he did it once, will he do it again? I'm starting to feel like a fool for forgiving. Should I leave him? But I love him so much, but this story haunts me.
