<human>: Can you summarize the given text in a few sentences?

My bother has recently gone to prison not sure how long for (estimated between 2 - 5 years, could be more), I haven't seen him for about 5 years, before that it was 10 years. The last time i spoke to him properly was about a year ago. I only found out about 4 weeks ago because He has sent me a number of letters. I have written back, but he wants to see me. he regrets not keeping in touch, and not making more of an effort. He is my brother and the only blood family that i have. But i dont know weather i should go and see him, we have never really had much in common, or even to talk about. I dont know if i should or not. So i was wondering if anyone has any advice or has been in this situation them selves.
<bot>: I haven't been in regular contact with my brother, recently found out he is serving prison time, and wants me to go see him. But im not sure if i could.
