he got his tux today! so i am not sure what to think

so after all that for the past 2 days and this morning telling me he would not go.. he went with my parents and was very happy go lucky about it.
then we went out for my bday dinner with my parents after wards and it was like nothing happened, but when i asked for my ring back he said he don't know where it is. so now more then ever i am confused. well i guess from here on in it's a wedding to happen but i am not sure i am going to try and talk with him and take it from there. wish me luck!
