I was born on 10th April 1989 and my boyfriend on 10th December 1988. Are we a good match?

It's not bad. However, you two need to adjust yourself to adapt to each other. Your BF is passionate and aggressive. He always fights for higher goals. However, you just want a cozy and simple life. You two don't contradict. He is far-sighted but you can deal with trifles very well. If you reserve your differences, you are able to establish a family together.
