How do i know when i should make an effort to talk to the person i like?

I hate not knowing whether to be the one to make the first effort to text or talk to the person i like, or if i should just let things be and see when i see her next time. Part of me wants to make the first effort so to remind them that i havent forgot about them, but at the same time i say to myself, if they really wanted to talk to me then they would text me. But then i think that what if they are thinking the same thing about me? I dont want to look annoying or vulnerable and sometimes i worry if i text them first that i will look annoying. It is also hard since this person is very flirty to me at times, and other times is very nervous and shy and avoids me. ( i think part of that is because they are in denial or the closet about being a lesbian). She knows i am a lesbian and acted very shy to me from the start ( i am very girly looking though). Me and this girl have hooked up before (and she made all the moves on me) long story short but she avoided me like the plague for over a year after the night we hooked up, but now she is back in my life now. She obviously hasnt accepted that she is gay yet but When i see her in person, at times she acts awkward shy and avoidy , and other times (usually when nobody is around) she ran up to me picked me up and gave me this huge hug almost knocking me to the ground! totally surprising me. Those are just some examples. When she avoids me or acts awkward or shy in person, it makes me think she hates my guts, but i obviously know she doesnt because then she would never be warm to me. And when she is warm it makes me think i should make more of an effort. The reason i think she doesnt text me first is because she is trying not to have feelings for me? what do you think? I just dont know what to do. But yeah any advice would help. ? :icon_bigg
