Hmm I always think that...once you get into a relationship,
definitely you will lose some of the freedom you once have as a
single...
I don't really restrict, unless I notice my dear becomes obsessed
with certain activities that will bring negative effects to him ie
playing too much games lolz then I will step in and tell him to
watch what he is doing. But havent come to a point when I need to
issue an official restriction yet 
As to meeting the people from the opposite gender, I am pretty
alright with it, he even stayed over quite frequently nowadays in
his ex-crush's house (with a group of other frens of cos) and I
never restricted that, provided he let me call him at around 1030pm
for a short talk. If he is busy during that time, he will call back
hehe. So I guess that's the only restriction: we have to talk for
at least 1/2 hour everyday, unless one of us is overseas or has
some other urgent problems.
