Am I wrong?

So I’m about 6 weeks pregnant with my first child and I’m freaking out! I’m sick all the time and emotionally and physically exhausted. Before getting pregnant me and my boyfriend had had a conversation about how he feels like he doesn’t have enough time for just himself. We don’t live together but hangout all the time and when he isn’t with me he’s with his friends or his needed mother. Before getting pregnant I had advised him to take time for himself every once and a while so he can relax. HOWEVER now that I’m pregnant I got a lot on my mind and I feel like he’s the only one I can talk to since we are in this thing together. We had plans to hangout tomorrow, but he said his plans changed for tonight and that he’s free. After vomiting violently and going through an emotionally breakdown, I want to see him earlier for some kind of comfort and reassurance that it’s worth it and that everything is going to be ok. But HE feels like it’s the perfect time to take some alone time and keeps bringing up the fact that I said it’s good for him and that now I’m making him look like an asshole for not wanting to see me. Am I wrong for think that things have changed? Am I being selfish for feeling bad and crying because he doesn’t want to spend time with me? HELP!!!
