Evening all,
Long time poster here but going unregistered for this post.
I currently in the middle of my most serious relationship - love at first sight, and over a couple of months, we hit it off and gave it a shot. Nearly two years later, we've moved in together and just opened a joint account - so pretty serious by my standard

Anyway, over the past number of months, our sex life has started to dwindle and what was every 3rd or 4th day is now every 3rd or 4th week. I've sat down with her as recent as last week and we've talked about it, as for me, a healthy relationship needs an healthy sex life - not like rabbits, but more active than we are at the moment. She's currently on medication and has said that this is the main reason why she hasn't been that way inclined, one of the side effects from what I saw, which is understandable and I've taken that into account.
As my previous relationships haven't been this serious, I find it hard to gauge when I'm being unrealistic, hence my lovely post. She has said that she feels as if she doesn't get out to see her friends as much since we've moved in together (something which I've never stopped her from doing) and that she'd like to make more of an effort, to which I said work away! She has been out a good few nights for 'girls nights' with the inevitable male straggler or two. Last week, she asked me if I would mind if she took two days off work and headed to the Galway races for 3 days with a friend of hers and the aforementioned stragglers. The last time she went out with this female friend, she ended up coming in at 5am, barely able to walk and vomited in the bedroom, hence why I'm slightly confirmed. This particular friend turns heads when she walks into bars, as does my girlfriend, but she likes to play men and when she heads out is only after one thing. The two that are heading with her are two male single colleagues in their mid twenties who haven't a whole lot of interest in the horse racing and more so everything that comes with it.
My question is - am I overreacting by thinking that most couples would be a bit put out by a partner heading off on the piss for a couple of days? I met my girlfriend at a time in her life when she was in a relationship for the previous 3 years and they weren't in the best place, which I could relate to how we are now I suppose (short tempered, mood swings etc). Should I be worried about her heading away or am I over-reacting?
I'm sorry if this sounds very long winded - I'm just a bit muddled by it all.
Thanks,
AM.
