Coming from personal experience, it's not worth it. ๐
I have spent time getting to know people who have acted this way. They seem really interested in you as a person with very obvious flirting, then when you ask them out, they say you are not their type (which can be really specific) or that they have a boyfriend. ๐
The good thing is that I usually find this out rather quickly. Rather than having a "friendship" for months on end and developing a false sense of connection, I can have peace of mind knowing where things stand between me and the other person.
For you OP, find someone who responds the same day, who is willing to make time for you and support you. ๐ฆ๐ง
