What you do is up to you, but personally I would not do this. I've always been clear in my mind, I want my bed for me and his bed for him! Main reasons, I am quite restless and also I know too many parents who have fought a move child to own bed at 5 plus years old battle.
From what you write my only initial thoughts are: your husband is away till August, that's a long time to let a little one get used to the idea that it's the norm to sleep with Mummy. What happens when Daddy gets home, will 3 in the bed be a bit cramped, what is your husband's thoughts on this because if your son is then moved to his own bed who do you think he might be a bit miffed with?!
By bringing your little one into bed when he wakes and cries you are teaching the result of this then means they get to move to Mummys bed rather than how to settle by themselves.
The battles of moving a child to own bed when they are used to sleeping with the parents is not fun, but if you are prepared to take no nonsense when you want to do the switch, then realise this now.
In my family, not allowing our child into bed with us to sleep has been a golden rule that was stuck to, until last month! He is 3 yrs next month. He awoke at 2am and would not settle from a nightmare and I was so tired (husband away) I brought him into bed and within 10 mins he said Mummy I want to go to my bed.
I was somewhat astounded by this, so we went back to his room and he settled happily. Think though he is one of these rare types that actually loves his own bed, he wont get out of it in the morning, he prefers to call for me to come in, though he is more than able to get out!!
