Everything I have read about MLTR says honesty is the only way. If you are honest from the start then no one can have issues with you or your actions. If they are not cool with the situation they don't have to be with you. It's the deception which is wrong.

So that's the theory but how do you put this into practice? If you are honest from the start, e.g. day 2, then they will probably think you are a creep and will cut and run. If you don't tell them, go out, sleep with them, and wait for them to ask you then it's likely they would claim to be deceived as well. Sure you haven't lied but you have self-disclosed which ultimately comes to the same thing.

Here's a recent situation which I handled badly:

I met a girl on a train and spent the afternoon with her (instant date). It's unusual for me to find someone living such a similar life. We clicked and I thought she was a really cool girl. She was also stunning. I texted the next day and didn't hear anything so forgot about it. She called a couple of weeks later around 10ish. We had a chat, was cool to catch up and we mentioned meeting up next weekend if we were both in town.

The following weekend I am meeting the girl I am in an open relationship with on Saturday night. I want to catch up with my mates so I go out with them, she goes out with hers, and I agree to come over to her place afterwards around 10pm. I get a call from train girl who says she is just down the road so will come and find me for a drink. I tell her I can't be long as I am going to see a friend at 10pm.

Train girl turns up looking hot. We chill, chat, drink, smoke. She is being friendly but I don't get any IOIs (I am doing a bit of kino). I'm not phased. This girl seems interesting so hanging out for a drink offers value to me. I have guaranteed sex later so there is no desperation.

Time passes and I tell her I need to go soon. She asks if it's a party. I say no just a friend hoping she would take the hint. She then asks if she can come with me. I say no I don't think that would be a good idea. She digs a bit and I tell her it's this girl I've been seeing. She gets a bit pissed off and says you didn't tell me you had a girlfriend. And that she feels a little silly. I tell her she's not my girlfriend although I don't have a word to describe her (My primary? Sounds like a player). I find myself justifying the situation 'I didn't ask you out, you just came along to meet me. I wasn't deceiving you' despite having done nothing wrong. We finish our drinks and I walk her to the bus stop where she looks a bit shaken. I give her a hug and kiss, jump into a taxi and say good bye. She says keep in touch.

So how could I of done this differently? I guess I shouldn't of agreed to meet her. But then again if honesty is the best way this would of come up sooner or later; albeit in a less in your face 'right I'm off to fuck another girl' kind of way.

I've never been in this situation, so forgive me for speaking from a place of total inexperience here.

When she said "you didn't tell me you had a girlfriend" I would have called her on the emotion. "Aww you're jealous! I think that's adorable." Saying adorable is key. Saying that she's jealous without saying it's positive for you will sound like an accusation and make her more angry. If she presses "Yeah fine, but you still didn't tell me." I would have flipped it on her. "She's not my girlfriend, but yeah, I didn't. I haven't known you very long, and I don't want you to judge me before you understand who I am."

That's perfect. It brings her attraction out into the open so we both acknowledge it's there, whilst being flirty, and yet defusing the situation. She can't deny the jealousy, or in turn the attraction. What other reason does she have for being upset?

When this happened I was completely caught off guard. Not long ago I was struggling to get with a girl full stop! Multiple girl management is another level. I kind of just played up to her challenge instead of playing it cool. I will know better next time. Annoying as she was damm hot (completely crazy though). Oh well everything is a learning experience.

There's something about this one pub. The last two times I've been in there crazy / unusual stuff has gone down. Both times it's been an interesting learning experience but not worked out quite to plan. Will think twice before entering that place again
