In our 5 years of dating I only checked his phone twice. The first one was when he gave me his phone to use for few days cause mine was bad. I went through his phone and he was sleeping with many girls i know, I took him back after he cried blood that he’s changed, second time the same thing happened and he got worse, I realized he’s a serial cheat. I took him back after crying for 5 months, he gives me everything I need and all but this time I deserve better, I don’t know how to leave maybe i should go through his phone again and to know if he has changed or i should just gradually withdraw myself emotionally and leave without any heartbreak
