Normally we text all day and chat most evenings, but the past couple of days he's been quiet and not suggested talking in the evening. Last night I kept looking to see if he was online (WhatsApp) and no. Even if he was out with friends he would suggest talking afterwards or he's send me a drunk text at 1 in the morning.
I just have this really strong gut feeling he was on a date last night . I feel pretty devastated, we've been seeing each other for 4 years. I don't know what to do.
