Will my daughter and husband's relationship be ruined?

Okay, mamas here is my situation. We are moving in about a month and we had planned on my daughter (will be 11 months) and I moving about two/three weeks before my husband is able to wrap things up at his current job and join us. My daughter and her dad are very close! She cries whenever he leaves the room and she just really loves him. They spend about 3 hours a day together minimum. I am now concerned that when her dad joins us their relationship won't be the same because of the weeks they spent apart. Will she still be as attached to him? Is this a legitimate concern?
