Matthew 26 and Mark 14 explicitly say that only the Twelve were at table with Jesus as He instituted the Eucharist. Luke 22 explicitly says the Apostles were at table with Him. No disciples present at the Last Supper in the synoptics. In John 13-17 the only disciples mentioned were those among the Twelve (Peter, Judas, Beloved Disciple/John, Thomas, and Phillip). Gospels clearly indicate only the Twelve (aka no women) present at the table. 

The Acts 2 passage refers to explicitly refers to the community centered entirely around the teaching and ministry of the Apostles in Jersualem immediately following Pentecost. The easiest reading of the text suggests the Apostles are present in all events mentioned. Particularly the breaking of the bread.

The "wait on tables' phrase you mention in Acts 6 refers directly to visiting widows' homes and not the Eucharist.

And yes, Peter was married but clearly had left his wife to follow the Lord. My reference was to current Church discipline.
