He lied about his age by 9years for 5 years

I met a guy 5 years ago when I was 19 and he said he was 24. Two years into the relationship after not having seen any of his official (or identity) documents of his I became suspicious of his age and asked him several times 9over the years but he maintained he was only 5 years older. After some digging 5 years into the relationship I just found out he lied about his age by 9 years making him 14 years older than me. I am angry with him and hurt by the fact that he lied over and over especially considering the difference between his real age and the one he told me. I am also very uncomfortable with his age as it never crossed my mind to date someone as old as him. I also can't help but wonder what else he could be lying about. On the other hand, I have put in 5 years of my life and hard work into this relationship which makes it difficult to just walk away from it. Basically... I'm not sure whether I should continue with this relationship and marry this guy or I should just move on. All advice would be greatly appreciated.

My first question is, why has the relationship been hard work, or are you being figurative? Have you confronted him with your findings? He could have lied to you in the first place in order to start dating you, but felt like he had to continue lying. But from the sounds of him continuously denying it, it seems to be a big issue. You should consider walking away because he is still lying about something that you can easily over look now.

My husband is 16 years younger than me. That is not the issue. It is trust. Why do you distrust him after 5 years? I understand him lying about his age at the start. The two of you really need to have a talk. Was he married before? Do you do all the work in the relationship? It sounds as though you two are not really close. If you can fix this by really talking about your thoughts and feelings, marry him. If not find someone who is honest and fun who you can build a real life with.Even someone less than perfect is better than this.
