Just frustrated

I’m just pissed of lately I feel like my fiancé lately has lost all effort in our relationship. Yesterday on Mother’s Day I had to get mad and ask him if he was going to say something to even say happy Mother’s Day. I have had 4 miscarriages and he already knew the day was hard for me and didn’t bother to say happy Mother’s Day until I asked him. Then today I was going to see him and he went to a festival we were having ignored me the entire time until I found him then when I did find him he barely wanted anything to do with me. He told me to meet him at his house so I drove there only for him to text me he went to the beach with his brother and friends. I was pist and went home as soon as I got home he came home. I’m just frustrated with him
