His reasons for leaving were:

I’m boring and he craves adventure (friends and family say this isn’t true about me. I’ve always been adventurous)

I’m too bad tempered. I work full time, early starts and I admit to getting very tired

I have a good relationship with his family but they say hurtful things to me at times. His mum told me I was fat when I was pregnant,for instance. I tried very hard to not speak to him about these hurtful comments in the end because I knew it was tricky for him (I am married to him after all and not them). So I began to keep them to myself but he cited it as a factor for him leaving.

I don’t think there’s anything else I can do other than make myself into a better, calmer person. I’ve tried talking to him, he’s been pretty clear that this is what he wants. Thank you for all your advise.
