Me and my boyfriend have been together for 3 years and we've been living together for over 2, we've always been extremely faithful and although our sex drives are a little different (His high and mine low) we've never had any problems, we have little 'sulks' with eachother now and again but we always sort it out. Anyway, next week i'm going on a girly holliday with my mum and other family members and it's the first time me and my partner will have gone a week without seeing eachother in over 3 years! I was fine with this until a couple of days ago, i noticed he's on his phone ALL the time, he even takes it to the bathroom! So i know i shouldn't but i logged onto his facebook (I feel awful for doing it and now wish i hadn't) and he's been messaging girls, not the sleezy 'You look hot in that photo' or anything like that but it's girls he hasn't spoken to in ages and each one starts with something like 'we need to catch up' He's also mentioned to each of them that he's got the house to himself next week, no plans and they should pop over, another he's invited out to go shopping. I know this all sounds really innocent typing it out but it's not like him. He's not invited any guys round, and we had a lovely day together yesterday just laughing and talking and looking at the message times he was talking to the girls all yesterday - am i just being stupidly paranoid? I need someone else to weigh this up with an outside view before i start talking to friends. Sorry this message was so long, thank you so much for any advice!
