advice please?!

Sooo me and my other half have been trying for a baby for over a year, we have good jobs, own home, pets etc and now I am finally 8 weeks pregnant!! :) we were both so happy to find out the news and we have been so loved up. However, we have a couple of silly arguments over then last few days and twice now he has said ''I feel like just running away" or "I can't be bothered with you"..... So now I'm like I don't no what to do, we both grew up without one of our parents and we agreed we wouldn't let our child grow up the same way but now I'm just like I don't no what to do......
