Well all good news, tail up is a good sign. She's still getting to know her new surroundings, 3 weeks is nothing, some rescues it can take months. I would not leave the two alone together for now, it's to early, you don't know what her reaction will be with you and your husband being gone and she is just with Ruger, I would not trust the two of them alone together, if you want to leave them home separate them.
For what ever reason, she has claimed your husband as her protector, he is her security. I think it's wonderful she bonded with your husband so fast. A stray / rescue bonding with anyone that fast shows trust in that person. I know you feel bad but you shouldn't, be happy that she trust someone, she will come around but it's going to take time. Who knows, maybe she was beaten, abused by a female, she may be scared of woman, you will never know. Just keep doing as you are, feeding her, taking her in the car, gently playing with her, she needs to gain trust in you. She will come around, it's just not going to happen overnight, it could take months, so do not feel bad or sad, feel pity for this poor little dog that a human made her so distrustful of ppl, or maybe just women. Make sure you're the only one that gives her special treats, not your husband, she has to associate you with good things and there is nothing better then yummy treats. Poor sweet little girl, how can ppl treat innocent lil dogs so cruelly.
