Am I wrong for feeling upset about this?

I had a miscarriage before I met my boyfriend and he has lost a baby to SIDS. I remember one time I mentioned my miscarriage to him and he told me it wasn’t the same thing so he didn’t feel like I could relate to him. I was upset when he said that because I felt like he disregarded my feelings and me in general. It’s been months since that. Tonight, he was telling me about a new worker he had that was supposed to start. She worked one day and then had a miscarriage from what he said. And then told me he was “bummed out” about it. I asked why and he said “because I lost (his baby) so I know what losing a baby feels like. Miscarriages are no different for a lot of women. You still go through postpartum and stuff too. It can be really bad”. I called him out and was like “ohhh but when I said that to you, I thought you said it wasn’t the same?” He immediately tried to backtrack and was like “not the same but very similar” and told me to “stop being jealous.”

Sooo Your girlfriend uses it as a way to try to help and connect with you but “it’s not the same”. But a random chick at your job miscarries and you’re “bummed out” and feel all this sympathy to her??? Like what?? That’s the part that just gets me.
