Need Advice-long sorry

So my husband is an extremely independed person who is very much an introvert and likes alone time. He's always been into bike touring and before we met he had just gotten back from a 4 month solo bike tour of South America. Throughout the years of dating and now marriage, he has gone on several week to two week long bike trips around New England (where we live). I have never once said no to a bike trip because I know how much he loves them. He has been planning one for this spring for a few months now, and just this morning I had a thought a mentioned maybe going on a trip together since it would be our last time to be able to go before the baby comes. He flipped out, couldn't believe I would mention that since he already planned a bike trip which is his "one passion" and told me maybe I could find someone else to go on a trip with. All of this was through text because he's a work and it lasted for a really long time and is still going. I just mentioned wanting to go somewhere warm with a beach and he said sitting on a beach is a waste of time off and is about as appealing to him as a ten day bike ride is to me. I have been in tears because all I wanted wa some last trip together before the baby and it hurt my feelings when he told me to go with someone else. He also told me the only vacations he wants to go on are hiking or biking trips even though he knows I don't really like them. Then he ended the conversation by mentioning how incompatible we are and that we need to have a discussion in person tonight. I'm really upset. Are my pregnancy hormones causing me to totally overreact? Is he being selfish? And input or advice would be really nice. Also if I am overreacting please tell me haha
