Aww these pictures are cute, Pablo is such a sweetie! It's not uncommon for chis to bond more with one person, although so far the 3 chis I've had have bonded with me and my partner equally. It surprises me that you spend more time with Pablo, yet he chose his daddy. lol Maybe you need to get a second chi for yourself. haha
Although Lilo loves us both, she does tend to cuddle with me more and my partner was a bit jealous before. So he's happy now that we have Rocky. We can have one each.
