Is this rude or what ?!?

[Olivia]

Me and my boyfriend have been dateing 2 months now and everything is going swell. I love him to death and I think he is great. Yesterday I was on facebook and saw that he had changed his profile picture and its a picture of him kissing another girl on the cheek ! I know it's just one of his friends but I felt so angry about it. I feel like that is so disrespectful to me as his girlfriend, to see his lips on another girl and put it up there for everyone to see. I think the picture was taken before we started dateing but it still really bothers me. I really want to tell him how I feel about it but im scared he is going to think im one of those girls that get jelous easy or is clingy or overreacts about stuff. I was just going to go take a picture of me kissing another guy on the cheek and make it my profile picture but I really don't want to kiss on another guy, it would be wrong. Would you guys think something bad of your girlfriend if she complained about something like this? Am I just makeing a big deal over nothing ? Please help
