Multibit transaction is not being confirmed
Move your private keys to Electrum. I had this issue with Multibit HD since last summer. I sent my bitcoin from Hive (which had just become unsupported) to multibit hd. For over a year the transaction showed up on multibit as unconfirmed. The steps I took were: 


Recover the wallet words from the multibit hd wallet file
Use a tool online that converted the multibit wallet words to private keys
Added the private keys to Electrum wallet


As soon as I created the electrum wallet with the private keys it showed up as confirmed in electrum. I would completely move to another wallet altogether as multibit is deprecated, and I’ve seen this unconfirmed bug happen quite often, don’t use multibit anymore.
