Sounds like he is either board or more comfortable in the relationship regardless do something exciting together and defiantly bring your a game to the bed room afterwards
In the beginning the relationship is new and exciting. Every day you learn something new about your new partner. The interest is there.<br />
But if a romantic bond is not formed by one or the other then it starts to become routine and a little boring. I think that may be the case here. He has not formed a solid romantic bond. A commitment. His mind may be wondering what else may he be missing out there.
for a relationship to work it needs both parties to put the effort and commitment into it on a constant basis to make it flourish
it happens. with everyone.
any relationship, if not nurtured by BOTH parties, can start to show wear and tear.
