I can do this anymore

Hi I'm a young teen going through a hard time I've had a boyfriend for a year now I found out he looks at naked girls online and I thought he was different now I feel uncomfortable talking to him he would also make inappropriate jokes about people I know I'm planning on break up with him sometime this month because I'm also struggling with my mental health and insecurities there's just so much going on I can't stop crying I need some friends to vent to together and support eachother I just want to make some New friends because I'm all alone
