My husband didn't send me a message on Valentine's Day, but sent a message to her ex-girlfriend. Should I mind?

Sometimes don't be too sensitive, yours will always be yours, and you can't force it without your insistence. He already belongs to you, maybe he just wants to express to his ex-girlfriend: it's too late to go back. I already have someone who loves me very much. This is just a show-off. Don't care too much. Too much care and too tight will make him feel disgusted. You can be good to him, even better than before, so that even if he has that heart, he won't do anything.
