Here's the scenario: She thought she was in love with him and she told him so. Now they've been going out 15-18 months and she's not feeling the same way anymore. She likes him alot, enjoys his company and so on and does love him in a way, but she doesn't think he's the guy that she wants to spend the rest of her life with. On the other hand, he's falling more in love with her every day. He thinks she's the best thing that ever happened to him and ever will happen to him and wants a future with her. She knows this and is just kind of going along with it. At some point does it become her obligation to tell him how she really feels and/or move on? If so, how long until she has to drop the bomb? I would appreciate your considered opinions. Thanks!
