Are YOU still chasing love from someone who can't supply it?
Trying to get love from a person incapable of giving it, is like attempting to squeeze blood from a stone. The mistake that many make, is thinking it's because THEY are not worthy or deserving of a richly satisfying, reciprocal love.
This of course, is a tragic carryover from childhood, when we couldn't get the love we NEEDED from our parental units. In the absence of having our adoration for them returned to us, we accepted and assumed we weren't lovable or good enough.
This shit follows us lifelong. If we finally FIND someone who can adore us the way we need to be loved, we think something's wrong with them, because how they treat us doesn't match our entrenched ("undeserving") sense of ourselves, and we reject or throw away that source of comfort.
Don't LET your parental units win this battle. Get the help you need to learn how to start feeling lovable and good enough, so that you can let in the love from another, you've wished for and craved life-long.
