is he cheating on me???

[dfiant]

no this is not true, did not give him permission to mess around as much as he pleases. what we mutually agreed is that if we mess around with someone, we would tell each other that we did so. this was the main agreement. Right now it may be sort of an open relationship because we are far away from each other for a couple of months but prior to this it has been very much a monogamous relationship. the main thing that i want is him to inform me of any bits on the side he may have as i would not get as jealous if it was not a secret, that's what i feel.

Actually everything Bowyn said is not only true, it is also FACT.

Mono = one
Gamy = Union, sexual union, partnership, marriage

If one person has more than 1 partner it cannot possibly be monogamous regardless of weather there is explicit permission or not.

Your relationship is an open or polygamous relationship. In that situation it is impossible to 'cheat' unless you specify with your partner your wish for monogamy.
