I don't want to be at home while in laws are being hosted, is this a good thing or bad?
Why won't you want to be home with them there? This can't be for real.
Because I'm an introvert person who doesn't like to engage in social interactions.
I understand where you're coming from, but it's typically a good idea to keep a good relationship with your in-laws. You should try to break out of your shell a little.
Not happening.
Your in-laws are your family too now. If you opened up to them and let them socialize with you then you could have some fun. Maybe enjoy their company and have moments where you don't feel left out.
