The reason she elusively stated a few videos back for not receiving chemo now is that she is not supposed to have chemo prior to surgery. No other reasons were given by her. For any doctors who read this, would you please tell us why/if chemo is contraindicated prior to extensive surgery? The only reason I can think of is that is would weaken her, and she needs to be strong for that type of surgery.
I am not sure about the time difference between these two relationships, but, no one should be saying 'Thank God you broke up with him'. Tiroy is a successful engineer, seems like a serious fellow, and any young lady would be lucky to be his choice in life (I did some searching.) Tiroy also looks a lot better now than he did before, in my opinion. Tiroy and Tiffany looked very good together because they were of the same race, accent, language--just natural together. I think Tiffany was more natural with Tiroy in the sense that I didn't detect 'darling this' and 'darling that' with him---no such formality. She never mentioned the reasons for their breakup. Matt, of course, is a very nice person. However, if they really have been together and serious with each other for four years, why didn't Tiffany ever make a trip to Ireland to meet his father? Tiffany mentioned that she hadn't met his father yet, or at least that is what I interpreted from what she had said.
