For the 7th time? That's a lot. Be honest with yourself. I suggest you to give yourself some reasons why he broke up with you 7 times. If you feel like you cannot trust him again, then don't just don't. He is able to hurt your feelings again. The reason he is trying to tell you "I love you" " I miss you" he is probably just using you. This is going to get you fed up. I can't image if someone broke up with you 7 times in a row... if you don't want to get your heart broken then don't trust him.
