<human>: Can you succinctly summarize the text in 1-3 sentences?

Over the past two weeks my boyfriend has been needing more "me time" -- time where we don't hang out/talk on the phone/really have contact. We usually see each other 5 days/nights a week but this is now down to 1-2 times a week. He has also been traveling more for work. When he isn't traveling, he's living pretty much the same way, just without me around. Working, going to the gym, hanging around (not the going out type), etc.

I should also mention he is in a bad place with his job at a startup and is looking for a new gig. We had a talk this weekend, and he said he needs to focus on his career. He wants to take a break from our (pretty serious, almost living together) relationship in order to do so. However, I have been supportive, sending him jobs, introducing him to some of my contacts, etc., and generally feel like I've been an asset in his past job search and this one as well.

The need for "me time"/space happened right when I got a big promotion (about 30% raise included) at work. He claims it is not related, but I can't help feeling like it is. We now make almost the same salary even though I'm 9 years younger.

What I am wondering is if I should agree to taking this break/space/time apart. We were on track to get engaged soon (have been talking about it a lot, agreed on a pseudo-timeline, etc.) and this seems so out of the blue.  I  have been very happy in our relationship and I think he has too, but do not want to wait around if he's on the way out and just delaying a real breakup with this 'break' bullshit. Is he threatened, or just really needing space? Is he just a commitment phobe that needs an out?
<bot>: 34 year old boyfriend wants to take a break from 2.5 year long relationship; stated reason is to focus on career. Do I agree to a break, end it, or try to stay together?
