Pushing It A Little Too Far!

My boyfriend is really starting to push his luck! I've tolerated his continual tardiness but now it seems to be getting worse. Last thursday we had plans but then he phoned me about an hour before we were due to meet and said he wasnt coming. Thats fine, I hadnt long got home from work and at least he gave me notice. However, last night he really pushed me closer to the edge. He'd texted me that afternoon and said i'll meet you at nine. Fine, thats tons of time to faff with my new hair and pick out a cute outfit. Twenty minutes to nine and he texts me saying he will be twenty mins late. Okay, im running behind anyway as ive stood in the mirror for the last half hour just posing! (something I do all too often!). At twenty to ten, thats twenty minutes after he was meant to be here, texts me and says his car is blocked in and can't do anything till after 10pm when the owner is to return. Fine, whatever was the response. At half ten he shows up and instead of knocking like usual, sits in the car outside and texts me to say he's there! That just topped off the fact that he was an hour and a half late. To be honest Im really getting sick and tired of the continual excuses and tardiness, i dont know how much more I can really take. I do like him but i know he won't change so there is no point trying. This could be his downfall and if it continues in much the same way i'm going to have to really consider the situation. I don't want to break up with him, i do like him but to be honest I dont think I deserve to be treated like this. Patience can only stretch so far! (If you (K) have come across this, I'm sorry that I may have hurt your feelings but I'm only being honest about the situation!). xxxxXXXx
