Should I let him go?!!?

i've been dating this guy for 4 months now..we aren't exclusive but we are pretty close (nothing physical..he won't even kiss me unless we are in a committed relationship)...



the past few weeks, he's been acting a little strange...he messaged me two week ago saying his life was bothering him alot (stress from quitting his second job and his first job piling on more work. he might be switching jobs all together and both of his cars need major work too) so he asked if he could take some space to think about things. he also told me that he'd talked to his sister about us and told her that he wasn't sure what he wanted to do with his life (what job he wanted, if he wanted to move to chicago, etc) so he was hesitant to get into a committed relationship just yet..his sister told him that it was a good thing that he knew he wasn't sure..I gave him the space but he did call me twice during those two weeks just to see how I was doing and to say hi



last sunday, he showed up to my oldest daughter's birthday party..stayed the whole time and played with my kids (he got her a gift too)..he told me during the party that things were better and he'd just needed to think. we made plans to go out again last tuesday...we hung out last tuesday and had a great time..he told me he was happy to be spending time w/me again and when we first got to the bar we play quiz night at he hugged me tight for a long time and said "let's just hold each other for awhile"...when we said goodnight, he hugged me tight for a long time and said "It's so nice to be hanging out again"



we went out again last night w/two of my friends (both girls)..we went to a sushi restaurant and it was fun. he sat close to me and rubbed my back alot. while we were waiting for my friends to get to the restaurant, we walked into the pizza place next door to check it out and he said "we'll have to come here the next time we go out to eat"



as we were saying goodbye, I tried to hug him tight but after a few second he said "ok, well I should get going" but then he asked me what I was doing tonite and tomorrow....I told him tonite was free and he said to message him to see what was up..



I did message him earlier today to ask him if he wanted to see a movie I rented for us (he asked me to) and he messaged back saying "i'm not sure. I am going to work in a few minutes. I will let you know. I might take the night off"



while I'm cool with just wanting to relax and chill on occasion, I'm starting to get a bit annoyed at how he seems to kind of blow me off sometimes..what should I do?!!Should I let him go?!!?
Are you sure you know whether he means take the night off _for you_ as opposed to taking the night off _away_ from you..
But even so, if you didn't arrange a day to watch the video, you can't just expect him to be free. Normally people check if someone is free and then take out the video?
The bottom line is he enjoys your company but can't commit because he might let you down and he would feel bad about that. From what he told his sister, he doesn't know where he is going to end up and sees a whole life ahead of him. Some guys are scared of starting something because of "future considerations." It is a very practical standpoint and may mean the guy thinks with more practically with his head.
Still, from what you say, it is clear the guy likes you and it sounds like he is fluctuating between thinking with his head and his heart. So give him time and always be clear with him on your needs, communication is key here. You need to suss out if he is going to mess with your head or he genuinely just needs some thinking time. If you want, ask him more about his thoughts (not necessarily about you and him because pressure is unattractive) but about his dreams and ambitions so he feels you are "on side" and it may encourage him to set out a plan to reach his goals. You need someone stable, not a mindchanger.
