Looming Aloneness

My husband starts training for his CDL tomorrow.. and after 3 weeks-ish of training and working to get the license, he will be going on a one month long trip on the road. He may be gone on each trip for 3-4 weeks at a time. Knowing that this time we have had the last few weeks could be the most we see each other for the next few months has been the hardest part. Trying to spend time together without spending too much time getting annoyed with each other is rough. Our nerves are on edge, but we all know this is the best thing for us long term. If my husband puts 12 months on the road for this large company, he will be able to get hired anywhere making great money, and securing our families future. And I do have goals for personal growth and for my son while he is gone.. but first step is getting used to being the only parent around most of the time while my husband is gone.. first we get that taken care of.. then we move onto the goals.
