For many people, the issue is we are usually unrealistic with ourselves.
We become therefore infatuated with this significant other, into thinking: this is it that we fool ourselves. There’s nothing a lot better than this. Whom else have always been we likely to be with? We tell ourselves this to such an extent, that even though the partnership is destructive, we don’t desire to let go of because we’ve programmed ourselves into convinced that this is actually the only choice.
Most of us have grown and changed since middle college and school that is high but consider carefully your relationships in those times. Think of how “in love” you had been.
