Parsing a log file

I am working on a script and have had some issues with one of my functions.  As it stands, I am able to parse my log file and pull out if the user was successfully added or disabled.  But, I would like to only have 1 line per user, and the date/status would be set to the last occurance
Below is the function and a snippet from my log file.

(each line starts with a date)
2015-01-13 16:11:42,157 INFO    UserLib userLib: user backs (abcdefghijklm123456780opqu39erjk) successfully added
2015-01-13 16:11:42,188 INFO    UserLib userLib: user robi (abcdefghijklm123456780opqu39erjk) successfully added
2015-01-13 16:11:42,235 INFO    UserLib userLib: user acker (abcdefghijklm123456780opqu39erjk) successfully added
2015-01-13 16:11:43,311 INFO    UserLib userLib: user amb (abcdefghijklm123456780opqu39erjk) is now disabled
2015-01-13 16:11:43,420 INFO    UserLib userLib: user robi (abcdefghijklm123456780opqu39erjk) is now disabled
2015-01-14 16:11:43,420 INFO    UserLib userLib: user blah (abcdefghijklm123456780opqu39erjk) successfully added

Write-Host "Reading MFeEPE log on $computername"
$results = @()
$mfeLog = get-content ".\test.log"
#$mfeDisabledUsers = $mfeLog | Select-String -SimpleMatch "is now disabled" -simplematch "Successfully added" -AllMatches
#$mfeDisabledUsers = $mfeLog | Select-String -pattern "is now disabled","Successfully added" -AllMatches

#$mfeLog | Select-String -SimpleMatch "Successfully Added" -AllMatches | ForEach{
$mfeLog | Select-String -pattern "is now disabled","Successfully added" -AllMatches | ForEach{

$t = $_.toString()
If ($t -match "disabled"){$status = "disabled"}else{$status = "enabled"}
$start = ($t.Split("'(")).Split(",") #split input on , [0] = date [1] = the rest
$userDate = $start[0].ToString()

$TheUser = ((($start[1]).Split(":"))[1]).ToString() #returns User username
$TheUser = $theuser -replace "user"       

 $record = New-Object System.Object
 $record | Add-Member -Membertype NoteProperty -Name TheUser -Value $TheUser.Trim()
 $record | Add-Member -Membertype NoteProperty -Name DateAdded -Value $UserDate
 $record | Add-Member -MemberType NoteProperty -Name Status -Value $status
 $results += $record
}

$results | Sort -Property DateAdded | Out-GridView

My script shows
backs    2015-01-13 16:11:42    enabled   
robi    2015-01-13 16:11:42    enabled   
acker    2015-01-13 16:11:42    enabled   
amb    2015-01-13 16:11:43    disabled   
robi    2015-01-13 16:11:43    disabled   

What I would like to do is update the date and flip the enabled/disabled part if it is already there.

Any help would be greatly appreciated.

Thanks Mike
