Am I wasting my time?

Me and my ex have been involved for 6 years the last time we were in a relationship was 5 years ago he cheated and i broke up with him. It took us a while but ever since we always stayed in contact and developed a friends with benefits kind of relationship. Ive wanted him back for a while now but our timing sucks and we have our issues mostly him. He contacts me when he feels like it and if i him he doesnt respond or takes his time. We can pass each other on the street and pretend we didnt just see each other. So many things wrong with this weird and twisted relationship but point is after all the hurt and pain in various forms i honestly love him and always have since day 1. He has his good qualities but when hes bad-hes bad. I know he feels sonething for me and i try to get it out of him but its difficult.Ive tried to walk away several times but i cant leave him its to hard and never works out so i stay and try and fix the damage. This is a crazy situation and twisted but im just not sure what im doing anymore it feels like im wasting time but i also cant leave no matter how hard i try its to late im to far in.

hey it sucks but you kinda have to let him go. ... he is just playing wit you.. and when he is done he wil leave you for a little miss perfect. .. so before you get so invested walk away.... let him be the guy who go away not the one used u and dumped u..... am up for being proved wrong best of luck

You have gone back to him several times and that hasn't worked. Because it takes too to make it work and unless he accepts his issues and does something about it then this will never changed and as you have allready tried more than once then you need to end it with him and you can do it but you need to be strong and end contact with him compleatly otherwise you will never be able to move on. But you need to make the decison yourself and if you do decide that this isn't want you want anymore then after you have broken up then you need to end contact with him because this is the only way that you can move on and delete his number and online contacts and if he keeps texting or ringing you then you need to change your number. And get support from friends and family to keep you going forward and keep yourself busy with hobbies and going out with friends and when you get yhoughts about him then don't push them out but let them be there and gently move your attention onto something else and the thought will get weaker until its not important. And if you feel yourself falling back and thinking about reasons to get back with him then remind yourself of why you left him and what happens when you go back and if you do this then will get there and Feel much happier for it. Hope this helps.

Thanks guys your advice has been very helpful and is reassuring me even more that its time to let go
