How do I deal with my judgmental sister and my bf she will not approve of!

I am dating someone who I have been on and off again for a few years. I never shared this info with my sister b/c she is judgmental and we live a few hundred miles apart so the easier way was to avoid it. He served time for white collar crime but has turned his life around and I am very happy with him now. I've been widowed for 7 years and dated others but I do love the current bf and respect him for getting his life back on track. My sister is VERY JUDGMENTAL and I know she will freak out that I'm seeing him! The real issue is coming up...I invited her and her husband to the beach where I'm renting a house for a week in September. My kids know I'm seeing him and understand. I invited her before I reconciled with him and I invited him to come with us. How do I tell her and do I make up some story to avoid her coming? Do I just tell her now and also if she can't understand and be cordial, then don't come? I'm so torn, help!

It's better if you tell her. I can understand judgmental family members. Just tell her im with so and so, you are allowed to have your opinions, but i wont tolerate your negative ones. This is my life and if your my sister than you should be able to support and respect me. I know you are worried but if this is a mistake, this is my mistake to make. i think the important thing to express is that no matter what you will always make sure your kids are safe. He may not have ever hurt anyone, but being a criminal is something that scares people. If she starts spouting off, walk away. I wish i could help more, family is always difficult. I wish you luck.

thanks for the input.
