Help with my boyfriend?

K so heres my story and IF YOU READ AND ANWER THSI YOU ROCK!!!!! I have been going out with this guy for 2 months it will b on Monday... I REALLY like him and last I checked and my friends have told me he REALLY likes me. I was just wondering if I'm being overdramatic because I WORRY A LOT!!! We usually txt every day but the past 3 days i either txt him and he gives me short anwsers and when i say haahaha or sumthin he will say soooo... it gets old. Also "he has always been like this but ud think he would be more comfortable about it" at lunch he comes up to me and all my friends and starts to talk to us but he never stands next to me, untill one of my friends says why arent u standing next to your girlfriend? On monday he told my friend that hes been wanting to tell me he loves me and I had just told my friend that and so she told him I have to... later that night he said he was going to tell me sumthing but he forgot, well not really forgto but ya know and we kept talkin and he asked me if I knew what he ment and I said i have an idea and he said k... Idk if he still likes moe or not thats the thing cuz weve been playing basketball @ school and stuff and hes been playin with this other girl that like a week before he said he hated and he didn't even come talk to me. Me and him swim together and she told him that shes gunna join soon so... idk where this is goin now. Im 14 and hes 12 but age dosent reallly make a difference and I know we sound young and stuff but it's not weird where i live. I really really like him A LOT and I need some tips to be more flirty and stuff cuz when were together we usually just stand there next to each other. O, and we kiss like every day but we havent made out but we both want to but i don't want to in public and he can never go to a movie idk why.
