Depression has started again!

I was tryin so hard to not let anything bother me but lately I’ve been feeling depressed but only because my so called boyfriend hasn’t been treatin me right when all I’ve done is be there for him! Other night we had a massive row and he’s been blaming me when he caused it as I went the shop an came back an caught him watchin p**n.. I’d understand if we weren’t together but it just bothers me I love him dearly but I can’t tell him how am feelin coz he always has a go an leaves me on my own in his for his so called “ friends “ who always make him do bad stuff so can’t tell him anything! Don’t know what to do! Anyone? Negative comments will get deleted!
