Should I tell her how I feel towards her?

Aw, you seriously seem like the sweetest boy ever :) she should've understood that she was your first gf though and cut you some slack on the PDA stuff but anyways, I think you should pull her aside when she least expects it and be like "Hey so I know these last couple of years have been on & off but I really care about you and I'll try PDA if thats what you want, I just need to know you like me back just the same." If it doesn't work text me lol jk jk but damn you're adorable
