'then ask' and i said will you go out with me he said yes. i said i was happy so did he. but he didnt text me much or call me. i called him . talking wasnt much. so 2 weeks later i dumped him cuz i found out he was talkin datin with other girls. we only lasted like 2 weeks and i didnt c him at all in the 2 weeks. i was so sad. cuz by this time. since the day we met. i was in love with him. so then i didnt talk to him much.. but i did again. we 'hung out' again. so then he started dating the gf again. she made him call me one day and say he didnt wanna c me or talk to me again. i was soo sad . so i texted back and said y. she texted and said ur a ***** and made me lose the one i love. i said ok. bye. i was devastated. i wanted to die. so anyways a month later i have a friend call him and say hey we should all 'hang out' he wanted to but couldnt. made up an excuse cuz he didnt want me to kno he had his gf with him. she was sleeping. which i later found out by him. he told me like it was no big deal. anyways we 'hung out' once after that ..now i may see him this weekend at a fisherree thing but idk about 'hanging out' cuz il have a friend with me and shes not like tht. anyways i kno hes using me and all.. . but i love him so much... idk wat to do and he doesnt kno that i love him and im afraid illscare him away if i tell him..
