So there's this girl who I have been chatting with for a few months now and we have had our ups and downs but the thing is sometimes she writes with "<3" and ":*" and sometimes she does not. Like there comes a day where she's writing to me with hearts and then the next day she's like all cold and stuff. Even if I end every sentence of mine with a "<3" she just does not end hers with one. It just feels like I'm bothering because this is pretty weird it's like she's a different person. I just want her to know that I love her and I'm just not ready to tell her that if she's going to keep changing like this. I don't really know why she's acting like this and I would really love some tips from you guys. I want to know how I could make her fall in love with me. I think she knows I like her but it feels like she does not like me.
She also used to text me first a LOT until now. She barely texts me. I'm basically clueless here and I don't want her to be like that. I really like here and I would do anything to make her like me too.
EDIT: I got to know that she has gone through a break up recently and that she's trying to forget her ex. Can this be the reason she does not text me or why she acts all cold?
