Okay well Ders dis boy in skewl he's like my besty n he's a senior n I'm junior.well we Ben clse fr bout a year now. We use to no ech othr three yrs ago bt jst by nme dis yr is wen we gt to n Relly tight frends. Well we dnt gt to chill outside of skewl but during skewl we chill tgthr as much as possible.we bth r open to ech other. Wen eva ppl c us alne tlkin dey ask if we go out n we sy Bo jst frendz evn teachers ask if we r BF n GF n we sy no. Iono now I'm strtin to gt feelings but iono if its jst ppls questioning our frendshp is gttin to my head.also we cld b texting normal n out of a suddenly he bcumz flirtatious. Iono y cuz he tld me he likes girl n NY. Ppl say we Luk guud togthr. Lately tho wen eva he tlls me bout dat gurl I give him advice n opinion bt wen I msg him bout a boy he wont respond. Iono if these r signs he likes me or what? I dnt dare to ask him if he likes me tho? I'm kinda shy wen it Cums to these thngs. Any ideas on wat to do? Or ideas if these r signs that we bth r gttin feelings? And if I tell him wat I wnt in a guy he sys "sumone lke me :-)"
