Post season 2 and Foggy and Matt are not talking. Matt has tried to be civil and keep the lines opens but Foggy starts using his new job as as an excuse (he's too busy, he's seeing someone) and knows he is hurting Matt. Matt is struggling; he's mourning Elecktra and desperately in need of a proper support system. He's still talking to Claire and she continues to be the kick ass friend he needs but it is still not enough.

Nick Fury hears of Daredevil and wants to recruit him. He starts sending Avengers to follow and assist him before he makes a move. Completely up to you if there is a romantic relationship or if Fury can offer friendship and support for the vigilante side of Matt.

Maybe Foggy can try to renew his friendship with Matt but realises it is too late and Matt has moved on.
