They can no longer keep up the facade but feel compelled to try for love.
I don' think that's love, or if it is, it's a pitiful sort of love. One that's brought one by weakness, by fear, it's desperate (on the part of the "black hole", of course). I mean they don't cling on to the other person and force them to be someone else out of maliciousness, but because they're terrified to be alone.
Because I think they know that they won't find any help there (and perhaps no pity either) - in their own minds, so they try and beg for someone to solve them.
But it's not love.
