Been seeing someone for a few months and ever since he's been coming around to my house he's made an excuse to use my laptop - he then sits playing on it for the first hour or so that he's here.
He always makes out that he's "researching" something for both of us but that's just an excuse to get on the laptop - he then sits playing around on car forums for at least an hour.
We only see each other at weekends (and sometimes only 2 weekends a month) so it grates on me that as soon as he gets here he's more interested in playing on forums than spending time with me.
Its the same story every time - he gets here and then makes up a conversation which will inevitably lead to him saying "actually, I could do to look that up on the internet, do you mind if I get the laptop out?".
I've been very tolerant of this so far but past few times it has irritated me so weekend before last he turned up and started up a conversation about booking a weekend away - then said "actually, I could do to look up a few places on the internet. Do you mind if I get the laptop out?".
I was ready for it so said "no don't bother, we can look all that up later. Let's decide what we're doing tonight instead." He looked really put out and then said "well, actually I could do with catching up with my forums - I'll just get the laptop out, I won't be on it long ... " 
I wasn't expecting that so didn't know how to react but I was fuming and my irritability spoilt my entire weekend. I was more pissed off with myself for allowing it.
So weekend just gone he got here and started up a conversation about me buying a car (I had mentioned that I was wanting to buy another one) so he said "Actually, I could do to look at autotrader and see what's on there for you. where is the laptop?". So ready for it this time I said "no its ok, I'll have a look later. I'd rather us concentrate on spending a bit of time together so we've not seen each other all week!" (I said this cheerily to keep it light). He looked put out again and said "oh, ok well I'll just catch up with my forums then - I won't be long ... "
So I lost my shit this time and said "I said no, I don't want you using my laptop! You do the same thing every weekend - you're supposed to be here to see me, not play on forums! why can't you do all that before you come here? do you not think it's a bit rude to turn up at someone's house - someone who has been waiting for you just to get out their laptop and sit with your back to them playing on forums???"
He got all defensive and started with the "woah!! ok ok!! wow what's rattled your cage? I'm only on it for about 10 minutes at a time, it's hardly crime of the century!". I said "no, it's at least an hour each time whilst I'm sat waiting for you to come off it because I don't see you all week and I'm fed up of it. If you're not bothered about spending time with me, don't come to my house - simple as that".
Needless to say he spent the rest of the weekend sulking then went home early Sunday as he said he wanted to have a play around on the internet as he'd not been on it since Friday morning!!!
So jury - was I being a brat???
