If a relationship started from something more relaxed but ended up more commited, is it ok if one of them sleeps with someone else after 10days apart?

We started dating in January, and it was sort of an open relationship. After a while, without addressing it, we were a lot more committed, she also started sleeping at my place for many weeks straight. After going on vacation, 10 days later she sleeps with someone else, claiming it was an open relationship to her. Is this considered cheating?

[mandyfire98]

Was there ever discussion about it no longer being an open relationship? Especially because it started out that way?

[nik0102]

Not specifically but from the end of April we rtatted seeing each other almost every day, to the point she was sleeping at my place everyday. she was also constantly worried I might be talking to other girls,

[mandyfire98]

She shouldn't be worried about you being with other girls if you're truly in an open relationship.

[mandyfire98]

However ultimately communication is key with this

[nik0102]

So there were marks that is is evolving to a committed relationship, without necessarily addressing it

[mandyfire98]

Yeah but it's always best to fully communicate

If you did this to her she would have cried bloody murder. She's just saying that because you didn't explicitly make her commit and easy dick came her way.

[nik0102]

So is that cheating? What should I do?

[Juxtapose]

Get another girl. If she wouldn't tolerate you doing it to her, don't tolerate that behavior from her yourself.

One day or 10 days, it makes no difference.

[nik0102]

So it is cheating?

[Nikki1989]

It is not cheating if it is an open relationship.

[nik0102]

Didn't it evolve gradually to a committed one, with us living together essentially?
