I am 38 years old, female, and was not very sharp emotionally nor relationally as a young person. (I got taken advantage of alot!) So I can relate to your insecurity about how to deal with this. (the longest relationship I had as a young person was 4-6 weeks! I just got sick of people very quickly!) I would recommend that you not proclaim "love" until a longer period of time has passed. Two months can seem like a long time, especially in comparison to past relationships, but it really is brief. Love is more than a feeling it's a mindset that affects your behavior toward that person and true love is unselfish, always having that other person's best in mind. This takes a while to cultivate and practice. The strong emotions of "love" are passionate and fluctuating. I think it's best to wait and see how things progress. You should let her know that you care about her. Don't hesitate to tell her why you like her. Be specific. Talk about her qualities and how you value them. Tell her that your affection for her grows daily and that you're begining to become very attatched to her or that she is becoming very important to you. These statements help define and solidify your relationship without jumping too fast into the "I love You" stage. Many girls feel that you are somehow pledging yourself to them when they hear these words and their expectations rise. Then, if the relationship stagnates or dissolves, they feel used and hurt. I hope this helps.
