Help.He's never home. "Gone fishing"

My boyfriend and I have been living together for 5 months. I love him so much but he has a lot of hobbies and a lot of friends. I love this about him but it takes up all his time.
I really do not want to be a nagging girl friend. Any pointers on how to handle it or did you leave?
He works part time. And somehow he's   gone every single day till about 8 -10 pm
I feel so lonely. Eating dinner everynight  alone. 
He has a boat and fishing with the boys is his main priority. I'm not exagurating. Every. Single. Day. 
I'm thankful he's not out with girls or getting drunk at a bar but does that mean I should accept it?? If I do just accept it, how do I go about doing it?
I try to go with him as much as possible but I have two kids under 3. So makes it hard.
I wish he would compromise and give me at least 2 evenings a week. 
For what ever reason, evening is when it bothers me. Eating alone. Getting ready for bed alone. He's home for sleep and sex. 
Am I being unreasonable?
