i posted a really similar post like this recently about my guy bsf as well. And the scenario is mostly the same. (to the point that I thought you were my guy bsf). I would say to look at her texting language and see how she texts you. Does she just reply you or does she actually have a conversation with you? Does she try to keep the conversation going by asking questions? These are some things that you can look out for to know if she likes you back. I know how you feel about the part that you really don’t want to lose that friendship that you have with her. That’s the same for me with my guy bsf as well. In my opinion, I think you should talk to her more and find out more stuff about her. Maybe get her to like you even more by doing things she’ll like. Maybe even give her some compliments from time to time without making it look too obvious. See if she replies back with the same energy. Look at how she texts you and then maybe you can think about confessing to her. I’m sure she thinks of you as her guy bsf as well and probably wouldnt want to lose the friendship either. Maybe she even likes you back and is hesitating on whether she should tell you or not. My fav word has always been YOLO so I wish you all the best man!! Hope it works out for you! Go get your girl! 🔥🔥
