I can't make a decision please help.?

Like i wrote before my gf and i broke up after dating for 4 years. long story short after getting ready to propose her feelings changed and she just wants to be friends.
Now about a few months ago her mother asked me to come to a banquet held in her honor. Yesterday my ex called me and wanted to know if i still wanted to go and i have no idea what to do. If i do go am i sending the message that she can still expect me to do what ever she ask? i was looking forward to this but i really don't know now. Her mother asked could i still come too bc she wanted to give me something nice. My question is if i go to this banquet am i setting myself up for heartache and pain?
P.S.
Happy Belated Mother's day to all you mothers out there.

I understand what you are saying, and I think that it is true...
The ex will definitely think she can have her way with you...
On the other hand the mom really wants you to go...
If I were you I would except the invitation...
However when you are at the Banquet...
Just pay more attention to the mother..This will show the ex that you are not there for her, you are there just for the mother...
Also while you are there make sure you laugh and smile..
Girls hate to seeing a guy who is all sad... this make s them less attracted to you...
If you really want to be with her, show her that you are confident in yourself.. and don't totally ignore her either... Just play like you are friends...
You want her trust... and her respect...
And later on if another opportunity arises where there should be someone else, you should go for that other opportunity...
During this time where you and your ex are apart, you may find that maybe you are better off as just friends...
You never Know, if its meant to be it will happen..
Good luck

i would probuall not go. If your going to feel like a horrible person and have your heart broken, and Still have feelings for her, She would probually would want you to go because your her friend, nothing more. I would just stay home. If i were you i would just leave her alone

You just want to go to get whatever gift she has for you. It's not worth it, whatever it is. Don't go.
It's telling the world that YOU can be BOUGHT.
