I would wait a few weeks after she has been spayed, even two months, and see how she is acting. They say that spaying a cat can change their hormonal imbalance, and make them more docile. If she continues to be mean to you, don't be afraid to let her know it. If you're playing with her and she all the sudden bites you, get up and walk away to let her know that play time is now over. If she trashes things on purpose, take her to what she did and spray her with a tiny bit of water. If she's constantly not letting you near her, try to find ways to do activities within a distance she finds acceptable, and every couple days make it closer, and longer periods of time until you are able to do it right beside her. Cuddling takes time, but most cats will warm up to it and then love it. Some won't though, I won't lie, some cats will never be socialable, and that is just how they are, I hope yours will warm up to you, I must say, that is the first stray I've EVER heard of that didn't fall in love with their owners and were thankful for everything they got. GOOD LUCK! PS If her kitten loves you, then she may see the bonding going on, and want to join in. That would be great for you if she did.
