Immature Boyfriend? Or am I wromg?

Ok so I went out with my friends sat during the day to an outdoor bar. Apparently my BF had a problem with what went on sat and decides to send me an email through myspace Tues nite. He said how he doesnt believe what went on sat,etc. I didnt do anything horrible. The only thing I possible did was I ended up falling asleep at my friends house and I didnt call him. He called my gal friend who he knows and he knew i was with and spoke to her. She said I fell asleep. I then spoke with him on the phone and he was out with friends. I emailed him back 3 times explaining what happened sat and also how I feel about him. He loves me why wouldnt he just talk to me about this? He is ignoring my phone calls and texts. He is 30 yrs old..come on!! I know he has alot of stuff going on. He has a 3 mth old with his ex-gf which by the way he hasnt told me yet!! I actually found out sat nite by my friend who knows him. What is his deal? Its been 2 days and no response??? I dont know what else to tell him
