Call it what you want but all bonds can be broken (if I am not mistaken).
So if you see that there's no future in a relationship, then why still carry on ?
If the level of excitement is not the same as the first few moments being in the relationship, then better do something about it. Talk your heart out to your boyfriend, and figure ways out to work on the issues. Better solve it than to leave it stagnant like that.
Just not healthy.
Sometimes we will pretend, pretend that both of us are happy. But then I know, deep down inside, both want to be free. Only that, who voice it out first ? One will definitely don't want to hurt the other one.
Feelings, emotions, and all about the right chemistry.
If you already know that, he is not the one. Then, don't cling on him further. Set him free, move on and find a new love. Though not easy, but that's the way to go.
I really don't know.
Perhaps one will have to go through few rounds of relationship before deciding to get serious with the faithful partner, who is still waiting, somewhere out there.
