Search Results: using a condom

I just began a relationship... its very fresh... we have only known each other for a few months... but I like him, a lot. I don't have any REAL relationships under my belt & at 21 I'm hoping this can be one to mention. I wasn't really trying to be BF&GF so quickly but he started saying it & so i said you never asked me to be your girlfriend so he asked & i said yes.

but of course there is a problem: he takes hours to text back unless he initiates a convo... if i text him out of the blue i literally wait hours to hear back... I have a problem with this... i know everyone doesn't live with their phone in their palms like i do & when im around him he really doesn't pay attention to his cell.. but i feel like now that you have a Gf you would at least check your phone every 2-3 hours? as long as my bf makes me feel secure & i can trust him im not overly jealous.. but i just don't want to play the fool in this relationship.. this has happened 3-4 times where i text/call & i dont hear from him for hours he'll say he was hanging with his guys or that he was drinking or smoking or something & one there was another instance we bout a 3-pack of condoms and we didn't get to use it that day & a saw him a few days later & he "couldn't find it"... am I deluding myself by thinking he isn't cheating already? is it too early for me to be worried? we are already together so i can't back track & say its too soon for titles which it very well may be... what do i do now? i want to call him & say why the fuck does it take so long for you to respond? what did you really do with those condoms? but i dont have any real basis & i dont want to be the crazy gf accusing him of cheating this early on with no evidence... ADVICE PLEASE?
