The problem here is that whilst you seem sure of your love for your boyfriend, and can envisage having a child together he can't. This could be a matter of time, in that he may come round, either if you continue with the pregnancy, or in a couple of years time, and you can try again. However there's also a chance that he may never feel that way, either about committing to you or about having children.
So I think it's really important for you to work out what it is you want - and where you'd see yourself in 5 years' time. If he was to say to you today that he doesn't think he ever wants children - would that be a dealbreaker for you? Would you stay with him and be happy, if he said he didn't want children? Is having children something you definitely want in your future or are you undecided? These are all things it would be good to be clear on before you decide what to do next.
At 33, it's true to say that time is not on your side, I know many professional women who have focused on their careers because "it's not the right time to have a baby" and who now no longer have that option. Some are happy with that decision, others are not. Would you be?
FWIW I was a single parent of 2 children under 5, working full time with a career - and make no mistake it's hard work - but it is perfectly possible. I also travelled a fair bit.
Good luck with whatever you decide..
