I realize that it’s very hard to come to terms with things like this when one feels so dependent on others & so rejected by them…but Hashem truly is in charge.
That being said, because it is a lofty concept, here goes the practical side —
It’s not worth fighting to get into a club that doesn’t want you as a member on grounds that are ridiculous. Why would you want to belong to such a group?
In the same vein, why push to get into a family that has preconceived & silly notions that they will hold against you for no good reason? Wouldn’t you prefer going into a family that will cherish you for who you are & not judge you for reasons that are beyond your control?
Your in-laws will be proud of whom you are & where you come from & welcome you into their family proudly….
Don’t settle for anything less than that. And then, you won’t be settling.
