Very important: We all love you!!!

Dear Alice,
Remember I was very happy when you told me you two were together. I thought he is a good guy and the feeling was like seeing my little sister going out with a nice guy. Last night, I felt so sad because I felt your hurt. However, I looked at this in a different perspective that you are actually blessed because you found out everything within a very short period of time. You didn't get fooled by his kindness and superficial package which other women will get trapped easily. You're looking for a true relationship and your intuition was correct. You have lots of great qualities. All you need is time. Here're some thoughts for your reference.
Unfortunately, we're not teenagers anymore
and expecting to cement a relationship without intimacy is unrealistic. I perfectly know where you're coming from and it's not your fault.
This is clumsiness on his part. He didn't know how to romance you. This is serious business.
A guy who wants to sleep with another woman will not wait more than 2 or 3 dates. A guy only interested in sleeping with her would have walked away a long time ago. So he tried.
Intimacy will help make a relationship stonger, not always of course. But if the other ingredients are there, then it's like a cement it holds things together
You know what...you didn't really want him anyway. Otherwise you would have acted differently. It's subconscious. A woman will go to bed if she feels comfortable. I know you were starting to get comfortable having intimacy with him, but he is such a fool.
He didn't make you feel like you could trust him.
He didn't like to "talk" (the real talk). That's probably why.
You were just chasing a dream. You were hoping he would change. Don't blame herself, he is not worth it.
