I feel taken for granted

Ok so sorry in advance to have to write such a sucky question but here we go…

So I, female 36, mom of one , have my own place. My SO, 37 who is temporarily living back with his mother whilst he saves for a deposit to buy a house (he rented for years before hitting the nest) we have been on and off for the last 3 years. The overall ‘goal’ provided we are in a good place is for us to put our savings together and buy a home together. Meanwhile, whilst we are waiting to do this SO visits me approx 1-2 times a week. We live about 43 minutes to an hour apart depending on traffic. It is approximately a 39 minute journey from my house to his work place, this is in between his mothers house and mine. He will not commute to his place of work from my house, he will only come here if he has a day off the next day and he has 2 days off each week. I do not have the option to travel to his mothers house to see him as I have not yet met his mother and haven’t been invited to do so yet , so we are already very limited as to when and how many times we can see eachother. SO has what he would call a time consuming hobby creating animation videos which consists of drawing characters, animating them, writing scripts and story lines for the characters, writing notes and drawing scenes. He does this after work at home, he also sometimes will do this when he is over at my place 1-2 a week. We have recently got back together after time apart and he has requested that we postpone this meeting so he can refer to his animation notes and do his washing, this is when he could do washing at my place. Should I feel disgruntled by the fact that we are restricted as to how often we can see eachother because he won’t travel to work from mine , the fact that he wants to postpone our plans so he can work on his hobby and do the washing rather than come to visit and do some washing at my place ? He would probably also intend to work on this hobby during our time too. Should I be understanding and accepting of these circumstances? I suppose I could say I feel disheartened when he cancels our plans for something like this. Is it unfair of me to hope that he spends the majority of his days off over at my place considering he won’t come when he has to work the next day to allow more options to see eachother throughout the week?
