<human>: In a loving relationship but things have been lacking for a while. 

Barely any sex; I feel like we're roommates.

I've been crushing on a barista for a while, and thought it was harmless. Have stopped being flirty but still go to see him as he's eye-candy. 

Today, he gives me his phone number... and I take it. Tempted to break up with my boyfriend and have a fling. I do not want to have an affair. It's not fair to either me or my boyfriend but I've been thinking about ending our relationship for over a year now. Is this the right time?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Boyfriend and I aren't too compatible, but love each other. Sexy guy I've been crushing on for months gave me his phone number.
