No longer in love?

i am not sure i am in love with my boyfriend anymore. the first year he was doing pills and spent most of his energy time and money on it. he stopped and we moved in together. he now drinks every single night along with doing some prescribed other things. he never wants to go out but if we do on the rare occasion he brings a flask with him and drinks the whole time. i found out he was texting a girl i asked him not to being as they hooked up right before we started dating and it made me uncomfortable. he saved her number as someone else and every time we fought or he drank he would text her. when i confronted him he lied until i made him call the number, and he said he was hoping she wouldn't answer so he could still lie about it. we've been together for about 3 years now were both 22. he lies about drinking, money, a lot of things. i feel like maybe hes not a man yet and has a lot of growing up to do. don't get me wrong hes a super nice person and very funny, but i am thinking maybe he's better off as a friend than a boyfriend. i'm not perfect either but i can say I've never done anything to ruin his trust nor do i have some sort of addiction issue. i love him but am trying to figure out if i'm in love with him. i would feel bad if i left him...

It sounds like you've already made up your mind, and just need reassurance that you've done the right thing. You must be very patient and strong to have lasted in a relationship with a problematic partner, I commend you. Your partner is leading a very unhealthy lifestyle, prefers to communicate with his ex rather than with you during a conflict and he lies repeatedly. I think you are right in saying that he would be better off as a friend, I think you should call things off for a while and give him a chance to join a support group and maybe find out who he really is and what his life choices will be from now on. You need to look after yourself for a change, and get away from a toxic relationship. I wish you all the best, and I hope that you will be ok

You will eventually walk away from your BF because his habits are destroying your relationship. He is an addict and regardless of his age, he will get worse before he gets better. His problems are his to solve and you will only get hurt by staying with him. Your instinct is telling you now what you think of him and his actions and you're becoming tired of his behavior and your reaction to it. By all means support him from a 'distance' if you can but you're better off, for your own sake, apart from him.
