Lied to me about vasectomy and other things?

Do I end my 2 year relationship. He failed to tell me some things that I thought were importaint, I find most things out accidently through people that know him. I love him yes, we have talked about buying land together, dreams, hopes... but I wonder if i can trust him. He works away from home, sometimes 3-4 weeks away at a time. He's very social. Drinks. He's attractive. Things feel a bit one sided in the relationship, his hobbies etc seem to take pride of place.... Anyway, I just found out he had a vasectomy before we met, he never told me... we had used condoms and i had been on the pill..... He did tell me he didnt want kids (he has two older kids from long ago) but i had said i wasnt sure if i wanted to or not, maybe oneday as i have no family at all. When i confronted him, he admiited he had not told me for fear I would leave... the thing is, i would have stayed, i love him, but now im thinking i should end it because he has managed to decieve me all this time... please help me think through this logically....
