Don`t worry about the card. You did your part by giving him one, he may be feeling guilty about everything, so pretending not to see it works for him. These MLC`ers are thinking more than we know.
By all means, go see grandma, that`s your reason for being there with D1.5, enjoy the time with her while the IL`s are visiting with baby. You`re in control, so stay only as long as you like.
If you don`t want a D, don`t file, let H do all the work. His parents must be appalled at his new life. Dropping a beauty like you and his D1.5 for a 22 years old floosie. My IL`s haven`t spoken a word to me since H dropped the bomb, funny thing is we are still together 2 years later and all seems well to outsiders, yet still no word from H`s family. Trust me, it`s much better this way, they have their own problems, but knowing them the way I do and how appearances mean so much to them, I`m just swept under the rug. Me, my children and grandchildren are not acknowledged by them. Their loss.
The fact that H was going to be a grandpa, without having a child of his own, (H is younger than I) at 42 threw him deep into MLC land. The fact that my S got his GF pregnant didn`t help, how would that look to H`s parents. My granddaughter came into my life when I needed an angel the most, just like your little angel.
Keep up the positive attitude Breton, you are doing great!! It will take some time, but H will come around, albeit it may be too late for him.
By the way, I understand how good it can help you feel when men notice you. My H does notice this and sometimes I wish I can follow through with some of them, just to go out and have dinner with someone who is enchanted with me. The time will come for me and you, when we figure out the path were suppossed to take, until then, enjoy the knowledge that you are a desirable woman and some man will be so lucky to have you in his life, it may be our H`s, it may not.
