Ive been divorced for 6 months

Ive been with a guy that i met before my divorce but starting dating close to when it was over.

Im still getting used to letting go and coming to terms for things that once were that aren't anymore. My husband of 10 years and all the holidays and traditions we shared together. So each first holiday without him, I am sad, and depressed.

My boyfriend would like for me to go to his dads house for Easter today, I thought i could until today. I am depressed and sad. I am greiving. I don't feel like i am ready to get close to someones family right now. Ive been honest about how i feel and the process im going through to my boyfriend.

Should i push myself to go or is it okay for me to cope and grieve on my own time regardless of who i am with?
