Who should I choose?

yes it is wrong because you are leading him on you are letting him think that he has a chance of being with you forever. and if you say with him the more he will believe that you really love him and only want him. the longer you stay with him the more easier he will fall in love with you and in the end you will end up breaking him heart even more than now.

Yes!! thats leading him on and thats wrong. If he knew you felt that way he would sure not want to waste anymore time on something thats going no where only to be dumped for the other guy down the road. Do the right thing and leave your current boyfriend before you just hurt him worse.

it is wrong because you are still in a relationship.. but it sounds to me like you just want to be with who's available.. you were so sure not to get back with him when you had your current boyfriend but now that your current boyfriend isn't around you want to be with your ex coz now he's the one who's there.. on the other hand you say you still feel for your ex and that you will eventually get back in the future.. how is that fair to your current boyfriend.. how would you feel if you had both boys there, available.. who would you choose then.. why is he your ex.. must be for a reason.. it's a tricky game but don't be a cheater.. good luck.

If you know that your current bf doesnt make you fully happy then you have to end the relationship. It will be better for him because he can start looking for a gf that loves him as much as he loves her. Don't be mean with your current bf. That's using people!
