<human>: Can you succinctly summarize the text in 1-3 sentences?

My fiance and I have just moved into our own home a few months ago and I am really interested in getting a dog. We have both grown up with dogs, him more recently than myself, but they have always been in our life. My fiance's family dog died about 3.5-4 years ago and he swore at the time that he will never get another dog again (actually no pets at all again). I told him that it was okay, and that he didn't have to, assuming that it was a shock during the grieving period. All of this time later, I still feel him out every month or so and the answer is always the same..."no, no no. No pets allowed."

His reasoning is that there is no point in getting one because he'll just get attached to it and it will just die. He always points out how upset I was when mine died, and asks me why I would want to do that again to myself. I say that I would do it all again in a heartbeat and would not trade the 15 years of happy memories for anything. 

I would really enjoy a dog and I know he would too. Also, a far off point for right now, but I would like our future children to grow up with a pet as well.

How can I get him on board here? I'm discouraged and heartbroken that I can't get him to come around..
<bot>: fiance lost dog 4 years ago, vowed to never have another pet, he is still going strong on this thought and refuses to let me get a dog. Says it will just eventually die and isn't worth the pain of getting attached.
