How to write short messages to complain to my mother-in-law?

The following are my ideas for you, I hope you can learn from them.

Aunt, I have been with her (girlfriend's name) for seven years. We have lived together day and night for seven years. You don't trust her outside, but you can come over. I believe you also want your daughter to be happy, and I will take good care of her. You can always stay with us. It doesn't mean that I have to separate you when I marry your daughter. I sincerely hope to get your support and blessing. I hope that with your support and blessing, (girlfriend's name) can be at ease with me and we can be truly happy.

Hehe, you can also adapt it yourself, (* _ _ *) Hee hee. ...
