advice

okay ik i’m gonna sounds so immature when i say this but it’s truly how i feel but i’m a senior in high school and i’ve been with my boyfriend since freshman year and in the past we’ve been through some rough things but we’ve both decided to forgive each other and try to gain trust and all that but now he’s going to another school and i’m so worried, not just cuz of the past but my dad cheated on my mom this year so my trust right now is so bad i don’t know what to do i loce him too much to end it but trust is so important and i don’t want to always show him that i don’t trust him because that’s unattractive, any advice ?
