is this a small price to pay?

Decide what you can live with in your love relationship. 

Are you happy in this relationship? 

Can you live with her family not liking or accepting you? 

You need to decide if this is a small price to pay for your relationship and whether you can tolerate being excluded from or snubbed at family gatherings. After all, all love relationships have their own unique challenges! But if you are seriously upset or bothered by her family, and if it’s causing conflict in your relationship, then you need to decide what you can do about it. And, what you can do does not include changing your girlfriend or in-laws. 

 Remember that you can’t change anyone but yourself. Don’t ask – or expect – your girlfriend or her family to act or think differently. After you express your feelings about how you’re being treated (or mistreated) and after you ask what you did to cause her family to treat you this way, then you need to let go. 

You have to let them be who they are. Your toxic in-laws may not be able to accept you for who you are, but for your own peace of mind and soul, you have to accept them for who they are.
