First rule is control ur frame if she wants to spend time with u awsome if not, there plenty of other women who want to sleep with u as ur the prize,
If she telling u how she likes some other guy, be careful u aint starting to creep into friends zone, say how nice this guy is, so nice to the extent he seems boring and needy, never openly insult him, aim to build more attraction, maybe routine once uv built attraction to a degree, u could say, well its a good job i like him or id take u to a beach and we d dance around a fire naked drinking rum

etc...
Its annoying i got a simular problem, but i think sticking to ur guns is best, dont let him get in the equation, cus u want to attract her, and keep ur mind on that.. happy huntin. Deus
