Am I over-reacting?

My Significant Other of two years just drove 1,000 miles to visit an old girlfriend. They are staying together in a hotel in Miami, seeing shows, eating out, shopping and spending 5 days together. He insists it is all platonic...that she is his "best friend". When I tell him I am upset about it and that any woman would be upset about this he claims I underestimate him. Oh, and since he has no income, he is using my money for this trip. Am I over-reacting my being upset about this?

No, you're not over reacting and you're basically 'blind' to your so's actions which are screaming at you.

No offense but are you stupid? that is totally crazy! he is like majoring making you look a fool as if your paying for his stupid trip where he is most likely cheating on you with her! sorry but come on wake up! good luck u need it with him!
