Lindsay Lohan ditched snowboarder Riley Giles less than a week after their family Thanksgiving vacation. While some sources, going into the holiday, had expected an engagement announcement, the "quality" time spent in New York seemed to tear the young couple to shreds.

The two met at the Cirque Lodge in Utah doing mutual rehab stints in September.

In the end, friends say, "Lindsay gets bored easily, and she just reached a point when she wasn't interested in dealing with him anymore.

"Riley partied all week in NYC without Lindsay, when she asked him to stay in with her or go out and do things with her friends. The whole point of him joining her was to hang out in her hometown as a couple. Not to party all night long without her.

"Riley was really unpopular among Lindsay's friends and family. No one really cared for him, and Lindsay eventually started to see it."
