I need advice

Hi everyone, I'm in desperate need of advice. Two years ago I found out I have a brother, I found my paternal family who I never knew. My brother caused me so much stress for one year and I gave him a chance because he was this brother I never knew about.
Last November we agreed to meet, I traveled 6 hours to a place that was 10 minutes near his home.
He refused to meet me and accused me of doing this on purpose, he may have forgotten he was supposed to meet me. I waited around the city all day and he never responded to my messages ever again.
Yesterday morning, he sent me a message, he hopes all is well with me and my pregnancy is going smoothly.
I recently found out I'm expecting in December.
I believe one of my family members probably told him.
My husband doesn't want me contacting him.
I'm feeling very stuck because I wonder, has he changed, why has he contacted me after 6 months, no apology just a random text like everything is okay and forgotten about.
I helped this brother a lot last year and he hurt me so much.
I don't wish to have a stressful pregnancy but also don't want to be feeling regretful.
I'm a very nice and friendly person, sometimes that is my downfall.
Any advice is much appreciated as I can't talk to my family about him. Thank you
