I love my boyfriend but i really like [[him]]?

my boyfriend nd i have been together for almost nine months.hes the only guy i ever opened myself up to completely nd i love him soo much.but we've always had a rocky relationship nd i tried tellin him we need a break or i needed my space multiple times but he saids things like please no,or saids im the only one who ever made him happy but he jus acts like im doing it jus to hurt him or something.i dont want to hurt him but he nd i both have sum jealousy issues nd stuff.it really upset me when my cousin told me a mutual friend said that louis seemed depressed nd even told her he was depressed nd said we was havin relationship problems.i didn kno what to think because we wasnt or hadnt even had any serious problems for months.he tells other ppl stuff that he should tell me since im his girlfriend nd i even told him if you cant open up to me bout it but you can to her wy are we together.nd he also made a comment sayin if i was pregnant it wasnt his.he makes everyone think he is this perfect guy.he tells me all the time that his mom tells him hes worthless nd that he has never even had a birthday party nd stuff but she treats him good as far from i seen she even pays his car payment nd things.it jus kills me because we'll fight nd i always end up bein the bad person.i am sometimes a lil rude to him but i realize it nd i stop.but anyways we been thru everythin together i cheated then he did..but he didn even kno bout me cheatin i jus came out nd told him cause i seriously felt horrible bout it but he denied cheating on me for days until i told him i was over it i jus want the truth.so anyways that was bout five months back nd done with.but recently i met this guy named cody nd i like him...but i love louis.im so confused me nd cody has kissed but never farther then that.i thought louis was who i was going to honestly spend forver with or atleast a longggg time but when im with cody he rarely crosses my mind. were all young 18 nd 19 so i kno **** happens. i don want my family to look down or be upset either because they all love louis too.i jus need advise louis is such a sweet guy it kills me the thought of not bein with him nd givin him up but cody is soo fun nd hypnotizing i jus wish no one gets hurt nd evryones oka in the end.i dont want to have loved nd lost with him but also they say if you love someone set them free if they come bak it meant to be so plz jus tell me what i should consider doing.
