Finished Forever War on Saturday evening. This was an odd one.
Part Militaristic Sci Fi and part social commentary. I liked the militaristic element - specifically that Haldeman took into account time dilation as a factor of the war. The funny thing being even at the "end" of the war there are probably still pockets of time dislocated war in action. So I like the militaristic part.
I did not care for the social commentary which seemed to take the tack of: things only get worse as time progresses and the Golden Age of the past is something to strive for. Specifically Haldeman seemed to focus on the homo/hetero social developments of the future - which if I am being honest didn't seem to make any logical sense as a reactionary policy to external pressures.
The ending left me with questions which in this case was a good thing - I will definitely read the sequels (the version I have has all 3 books combined and is the complete version).
The thing that really stuck with me from my reading of Forever War was the time dilation. It's one of the few books I've read that I felt like it was handled appropriately, especially the fact that the war is finished but still going on as you mentioned.
As far as the homo/heterosexual relationships, I had just chalked it up to confined living spaces lol. I didn't really give it much more thought than that when I was reading it. Admittedly though, I was caught up in the time effects.
Also, I hadn't even realized there were sequels. I had thought it was a stand-alone.
At some point I'll throw in an update on what I've managed to read since my last post, but as I'm thinking about it, I've quickly realized that I strayed aimlessly from my initial to-read list. If I finished half of those I'd be surprised
