I first came into contact with boyfriend on Plenty of Fish back in April. We spoke lots on there and then on facebook and via text. Arranged to meet a few times but something always went wrong and we didn't end up meeting until July. Well, my phone went a bit funny earlier and took me back to those very first messages in July. Seemed funny reading all that back, telling each other about ourselves and being all nice and well behaved 
Then I read the messages from July. When we first met, head over heels, whirlwind romance - all day texts going into the early hours of the morning - all sweet things such as "you're amazing" and "can't wait to see you again xxxx" etc.
Now, we've been together since that first meet in July. Lots of happened since then, many cinema trips, many nights together, lots of laughs, lots of drunken conversations, lots of sex, lots of cuddles, weekends away - we've done it all.
So, I came back to recent texts from him. Gone are the "can't wait to see you xxx" texts and the "you're amazing xxx" texts and in place of them are just general chit chat texts "what you upto?" "bored, lunch soon" etc.
Sounds daft but I feel like we've "lost it" already 
We do see each other a lot, 3/4 times a week but isn't it a bit early to be settling into that "comfy" stage where we don't need to "try" anymore?
Is he losing interest or is it normal for texts to calm down and represent the real world after a couple of months?
