What to do If your girlfriend’s sister likes you

1. Access yourself

The first things to do is to take a moment to introspect and ask yourself some crucial questions. Ask yourself do you have any romantic feelings for your girlfriend’s sister? Also, analyze the overall health of your relationship with your girlfriend and whether you might be unintentionally playing a part in the situation.

Reflect on whether you might be inadvertently contributing to the situation, maybe because your relationship with your girlfriend isn’t great at the moment. If, after honest reflection, you find that you genuinely love your girlfriend and your intentions are clear, then your conscience is likely in the clear.

2. Don’t play along

If you’ve taken a moment to think things over and you’re sure you’re not the one stirring up this situation with your girlfriend’s sister, it’s crucial not to go along with her advances. 

You don’t want to give her the wrong idea that she might end up getting what she wants, which is basically you. Stick to your commitment to your girlfriend and set clear boundaries to keep your relationship intact.

3. Confront her

If you don’t play along and you notice that she’s persistently trying to get you to like her and, it’s time for a conversation. Give her a call and tell her you’d like to see her, and when you two meet, let her know that you genuinely care about her but not in a romantic way. 

Make it clear that these feelings could mess up your relationship with her sister, your girlfriend, if she is to find out. And you also want to avoid any negative turns that might lead to resentment between the sisters. [Read – How To Stay Friends With a Lady And Avoid Falling In Love With Her]

If you’ve had a chat with your girlfriend’s sister and she’s still not giving up on trying to get you, it’s time to loop in your girlfriend.

But you have to be 100% careful with this, try to approach it gently; don’t spill all the details about what has been going on with you and her sister. Just let her know that her sister’s been acting a bit off with you lately and you’d appreciate it if she could have a talk with her. This way, you’re addressing the issue without dropping a bomb that could strain their sisterly bond.

5. Cut off communications with her

Keeping in touch could lead to things going in a direction you don’t want, potentially falling for her if you don’t end things and ruining my relationship with your girlfriend, her sister. It’s a tough call but it’s the best thing to do to in order to protect everyone involved.
