love and marriage

so my ex is engaged. i havent talked to him for awhile and he was online tonight. he has been house hunting and wedding dress shopping with his fiance. this may be wrong or stupid but i am jealous. first of all he basically took our relationship and just continued on with another girl in replace of me. its like us breaking up never really happened. all of our plans are still going according to plan, just with someone else. while i am glad its not me, i just think it is so dumb. i feel like he is making a huge mistake, and i feel semi guilty. its rediculous if you ask me.
