rehome female cat (hawks praire)

Looking to rehome female cat. She's had a troubled past. Me and ex got her from Tacoma shelter. Has an obvious aversion to males, making me believe she was formerly abused. With the "ex" part in my relationship status, I hope to find her a better life. She loves attention when she comes out. Loves playing with toys and would love another cat that wasn't a jerk. She does not get along with my other cat. He's very aggressive and territorial (had him since he was 7 weeks old) at times and have been unable to get them to build a proper relationship. She's a very skiddish cat and usually spends the day hiding under my bed. Always feel like it's 1 step forward and 2 steps back. Anytime we get something going, the other cat scares her and restarts the process. She is a very overweight cat. Have tried multiple food types to try and get it down, but with how inactive she is under the bed, having a hell of a time.
