Two months in advance, lesbians always hinted that I didn't respond positively, and then I replied back and forth. Why can't I ask out?

I guess I'm sad, or I have someone else. If someone likes you and you don't respond, she may think that she is romantic and that you don't like her at all. In this case, don't contact her again, even if you contact her later. If you don't make it clear that you are pursuing her, she will probably ignore you, because she is afraid of being romantic enough to bother you. If you like her too, try to get it back. This time, you need to go all out.
