I started dating someone very casually last year. Due to physical distance and both being on the fence about serious relationships after a lifetime of those we agreed to keep it casual, date other people if we wanted and just have a wonderful fun time together on odd occasions. He was wonderful and for the first few months we had a lot of fun. But then life got in the way, we saw each other less and now I just can't be arsed... he's really lovely but I've just got too much going on to feel enthused about getting riotously drunk together and having a shag with someone once every 6/8 weeks. I honestly don't know what has happened as he is still lovely and hot but I've just got the ick a bit as well.
I'm starting to feel like I want a partner again to share stuff with as well if life allows. I know it should be easy given the nature of our relationship to just say this but I hate talking on the phone and Im not sure when I'll see him next. In fact our next planned meeting is ages away and involves an event that we booked in a moment of spontaneity that was very exciting at the time but is now just filling me with dread about the expense and my heart isn't in it.
I've not been dating other people but I know he has and I've not got a problem with that at all. It suited me perfectly at the time. But I've started to have feelings for someone I've known as a friend for a very long time and I would like to pursue it (if he's interested) without having to explain my somewhat unorthodox current situation. Would sending a text be so terrible? I'm just not very good on the phone... so much so that when he's asked me if everything is ok as I seem a bit off I've just said it's fine I'm just busy 
. I've obviously lied about it being fine so I'm just going to look like a bit of a dick when I break it off. It shouldn't be such a big deal as it's not serious or committed but my anxiety is through the roof as I've handled it so poorly.
