I've been using forge for over two years now, and I've never had this issue. When I click "play" on the launcher, the launcher does what it normally does (stay open), and Minecraft just won't load. When I changed the launcher to close when Minecraft launches (default), the launcher was the same way.
I'm using 1.6.4 because one of my favorite mods (Dragon Block C) is only on that version at the moment. I installed forge 1.6.4 (the recommended version), and next thing I know, I have the problem. I changed the profile to Forge 1.7 and loaded that, same thing. I then went to my regular non-modded profile, and it loaded perfectly fine. What's the problem? I downgraded to Java 7 for 1.6 (as Java 8 makes 1.6 laggy for me), and it still didn't fix anything. My regular profile is 1.8.2.
Here is what my launcher says:

You're still running java 1.8. Either install the legacy java fix from lexmanos, link for which i don't have at the moment, or hit edit profile, and change the jvm executable file path to point to a java 7 file.

I found the Java 7 location, but I can't make it work (I'm copying/pasting the file location in "executable", and adding "\javaw.exe" afterwards). Here is what I'm putting in the section: C:\Program Files\Java\jre7\bin\javaw.exe
Never mind, I got it to work. Thanks!
