My bf & I were together for 9 years with no pets, although I am a MAJOR animal lover and he is not, plus he has allergies too. After 9 years I BEGGED for a dog. We got our first yorkie. My boyfriend decided after that he didnt want to get married and have kids, the dog made him realize how much work and responsibility a family would be. We broke up.... after I was able to look back on the relationship, I realized that its a LONG life to live when you cannot EVER have what you want (pets, dogs specifically) bc someone else feels the need to control you in that aspect by saying they don't like them. (its taking control over your life that he is doing)
Thats all I'll say......
good luck with your decision!
