God forgive me

So I don't feel like I would relapse the next days and I can control my thoughts about porn and sexual memories but today I saw a girl where my lustful thoughts were to big to control them (I looked way too long in her direction and not only in her face). Can't lie, she was a 10/10 and also dressed in such a way that you can see a lot but it makes me feel bad that I didn't have my thoughts under control. Lust isn't even a bad thing, God created us to feel attracted by the other gender but we must control our thoughts and feel only attracted by our wife/husband. I feel bad and guilty that I looked at a girl with lustful thoughts. I image Jesus stands next to me, looking at me being disappointed and ashamed. "He can't love someone like me" is my only thought at the moment but I know he'll forgive. Hope I get my thoughts under control so that this doesn't happen again.
