Scarey123 I just don't get the silence - three months is an investment in a person in my mind - he's showing you who he is though, isn't he? I wouldn't believe any excuse he comes up with either TBH.
So, your scenario is interesting but are you absolutely clear in your mind that it would not be a 'relationship saving method'?
What would you really do if he were at home and welcomed you in? Would you go in and be the relieved grateful tail wagging puppy who's magically morphed into a fuck buddy and puts up with silence as and when he feels like it? (sorry, I'm not accusing you of that - just using extreme language to get the message across).
I just don't buy this crap that a man is entitled to withdraw into his fucking 'man cave' without notice after three months, a key and holiday talk. If he's feeling suffocated or similar then he should say something and just ask for a bit of space but to unilaterally withdraw communication privileges is just shit behaviour beyond belief.
