Is it appropriate for my boyfriend to snap a female friend at 1am? ?

So for some reason I had a gut feeling to check my boyfriend's cell. I found a voice clip that hasn't been deleted where Friday night, at 1am, my boyfriend sent a voice clip to a friend that he know for almost 10 years. He said he was on his way home (when he told me he stated home all night) and gave a specific location of where he was driving (cross streets). He stated he was sorry he didn't go eat at her house and he would go over but it was so late but wished he could go to give her a big kiss on her cheek. This isn't the first time I notice a message between the 2 of them in the middle of the night. I love him and he says I'm the love of his life. Advice very much appreciated.

Oh and we are currently no longer living together because 2 weeks ago I found he deleted some messages where a new female friend from work stated "you passed the test, my puppy likes you". He explained she needed a ride home because her car broke down, so he gave her a total of 3 rides home. On 3rd she offered to smoke him out and he went inside to smoke on patio (per his story). I don't know what to think. He doesn't see anything inappropriate with his actions...
