well, i can kinda relate. i'm thinking part could be b/c you're home with her more than your partner is, and maybe she's really wanting both of you together, all the time. they're pretty smart by 14mos, but can't really grasp the concept of going to work, or time, anything. when i had my first, my bf worked so much, he barely saw her the first year. i can't even say she and i were all that bonded, she loved being held by anyone, and didn't seem to care about me until she wanted to nurse. lol. when her dad changed jobs, he was home for 3 weeks in between, and they formed an instant bond. and come to think of it, it was at a similar age, she was 13mos then. anyhow, don't fret too much, things do change. mine is 8 now, and though she favors her dad, she's likes me just fine too.
i actually left overnight once, when she was about 4, figured she wouldn't even notice i was gone. she was waiting up for me the next evening, and so excited to see me back home. i honestly thought i was nothing but a babysitter to her, but i think just being together so much, she just didn't have the chance to ever really miss me. i think its fine, and normal, and many parents have kids who are clearly closer to a certain parent, at certain times. there'll probably be times in her life she clings to you more. hang in there, its really normal.
