I'd just say I think this person is not a manipulative, selfish, self serving prick. I have dated a lot of those, was engaged to one and I'm no stranger to being in a situation where I like a man more than he likes me (happenned many a time!) or being strung along (also too many times) or where I am being used for sex (or at least they have tried to) and nothing about this man says he is any of those things.
I have been on a gazillion dates. If I sent you all the bll shit messages and rubbish men say to me you'd vomit in your mouth a little bit (I know I have) and this guy is nothing if not honest and upfront.
It might be a case that he doesn't like me enough to want a relationship, or it might be that he was certain he didn't want one and now he is rethinking or it might be that he just enjoyed the affection and closeness, I honestly don't know because we only really had a text tennis match which isn't the best.
I'd never done "no strings sex" before with anyone - only ever with boyfriends - and as sex and nights spent with someone else I was feeling like the ones we were having were up there with the most romantic, sweet, intimate that I have ever had and something was saying "umm...this doesn't feel right", and I was feeling attached, bit concerned about it and frankly wondering what his definition of FWB was.
I don't think he is a dick though. What he sent me was sent to me to explain all the diferrent things he thought and his behavior and that was actually a nice thing to do because his intent from the tone of it was not to get me into bed, but to make me feel better.
At the end of the day though, if he is not willing / wanting to make a proper go of things with then I can't continue being intimate with him because I want to give more than he does on a day to day basis and that's going to make me feel bad.
He's also never done this before, and I think he is just also a person who doesn't really know what to do all the time; just like me. Not to say I am holding out for him to give me what I want - but more keeping an open mind.
He hasn't actually done anything wrong. He asked me to be FWB. I agreed. Slept together 3 times and I got attached. If being overly affectionate is his only crime it puts him head and shoulders over the bunch of wankers I have dated and TBH he's been nothing but honest with me which is refreshing.
I do really like him, but I'm not daft enough to continue shagging smeone who wants no future with me, so unless he comes back and says he does I will have the self respect to walk away so don't worry.
Incidentally after my first foray into this marzipan, I do agree with you. I think it's an invented term for entering into parts of the traditional idea of a relationship and skipping the ones that don't suit. I can imagine it works fine if you have no feelings for someone, but then if that's the case I (personally) would not really enjoy the sex bit as much.
