You meet a woman and after the first couple of dates, she tells you that she dates you only because you need her.
She felt bad about how infatuated you were with her and she only dated you for your own sake. You really weren't her type and she really didn't like the way you lived your life but she felt obligated out of her selfnessness to meet your needs. She sacrificed all of her selfish romantic desires and just focused on how much you depended on her. She was so selfless and altruistic in fact that she mostly admired your neediness and how sad you would be if she left you. She loved that your entire happiness depended on her presence and thus felt altruistic in her act.
Would you accept a "love" of this kind?
What you're describing ain't "love". It's two people whose psychological pathologies intermesh to give them the illusion of "love". Only the clinically codependent (or those who suffer from some other serious mental affliction) would think that the relationship you've described above qualifies as healthy.
Just guessing, but the "she" in your story above is a sociopath who will wring her victims dry and toss them away like so many old rags.
Good luck!
