I need help. i have no clue what to do about this guy...

I'm sorry but you kids take the term "love" way too lightly.Believe me no matter how "in love" you two seem to be you'll see in the future it's all just puppy love. So all this crap about him loving you is completely bs. And another thing NEVER make yourself that available to a guy. You should've ended the conversation when he was like " I cant choose between you two" who the hell does he think he is. What does he mean he cant choose, As soon as he said that you shouldve put "NO! I'm not up for grabs when you make up your mind, you should be lucky I'm even considering you. Are you crazy? Whatever if you have to think about it then there's nothing I can do with this relationship. Go ahead a go out with whatever broad you tryna be with because there's MUCH more where you came from". Even if you didnt say that you shouldve been thinking it. Forget about him your just kids there's many more relationships to come and you dont need to waste your time thinking about this "wanna be player".
