What to expect after a break up from a long relationship...?

[angel]

After 1 month of her breaking up with me....we were together for 9 1/2 yrs. I found out she was going out with a co-worker behind my back. She got together with him asap. On xmas day she gave back 3 of my boxes when we used to live together for 6 yrs. She is always mean toe as if the one who did her wrong.... she talks to me with anger inside her. We both have the same friends (most of them are social media due to our online business we have). Most dont know of the break up...she doesnt want to let them know of it. I care for her and wish her the best with this new guy who also knew I was her love. I know friendship is way too soon... What should I expect now? Will see just ignore me...delete me from her mind...or should I just let her be and if she ever comes back contacting me as a friend...allow her? Pls need advice and no harsh remarks pls. Thank you all.
