My bf and I have been dating month and half it’s been amazing i have never felt this way before. Sometimes I feel like I share to much and am to clingy with him but when he’s not around I just want him. The week I haven’t been feeling well my head hurts lot my stomach just hurts. The last two day I didn’t see him but I really really wanted him. He came over today I just didn’t feel it. It upset me tho I really like him Idk what was wrong today
