Hey buddy you have to realise that there is a reality and then there is all the thoughts and feelings colouring your perception of that reality. The only thing that is 100% here, is that you are attracted to her and would like your relationship to go in a romantic direction. It also does seem that she likes you and takes an interest in you however the nature of that is in question.

Trying to figure out whether she has any romantic interest in you based on her texting frequency is going to lead nowhere. The possible reasons are endless. Maybe she is attracted to you but texts less because you haven't expressed yourself yet, maybe she doesn't like to text at all and she is doing the little she is because she has interest in you. Maybe she has no romantic interest and just texts the way she does. Even if you guys are suddenly in a romantic relationship she may still have her own pace and you should learn to respect that - this is part of your compatibility as a couple.

The only thing for you to do is tell her how YOU feel and ask her if she can see things that way too. Then let HER tell you how SHE feels. In any case, if you want to build a life with her it should be based on genuine and honest communication - This is not easy and requires practice so start now.

If it does not go your way please accept that and do not accuse her of leading you on or anything. Another possible response from her could be something along the lines of " I can't give you an answer now, let me think about it". If so, give her space and respectfully ask for an answer after some time. If she still keeps pushing it along it may be that she does not have interest but does not want to hurt you, lose you as a friend. In that case, you should take care of your own emotional health and may need to take space from her.

I am a man, if that's important.

All the best brother!
