Skipping the choose relationship form when only one relationship available

I redid the user_relationships_request function. When requesting a relationship, when there's only one relationship type available it's nice just to set that relationship directly without having to choose type of relationship and then pressing the submit button. Thus I borrowed the submit function and put it in the function. It checks if there's only relationship and if so just submits the info and redirects back to the requestee's page. Now it incorporates validation but I'm not sure its completely right which is kind of ugly

/**
 * Request a new relationship with another user
*/
function user_relationships_request($requestee_id) {
  global $user;
  $requester = user_load(array('uid' => $user->uid));
  $requestee = user_load(array('uid' => $requestee_id));

  if (empty($requestee->name)) {
    drupal_set_message(user_relationships_get_message('non_existant_user'));
  }
  else if (!user_access('can have relationship', $requestee)) {
    drupal_set_message(user_relationships_get_message('not_accepting_requests'));
  }
  else if ($user->uid == $requestee_id) {
    drupal_set_message(user_relationships_get_message('self_request'));
  }
  else {
    $form = user_relationships_request_form($requester, $requestee);
    if (!$form['rtid']['#options']) {
      drupal_set_message(user_relationships_get_message('too_many_relationships'), 'error');
    }
    else if ( sizeof( $relations = user_relationships_types_load() ) < 2 ) {
		foreach( $relations AS $relation ){ $rtid = $relation->rtid; }
		
		  if (user_access('can have relationship', $requestee)) {
		    if ($current_relationships = user_relationships_load(array('between' => array($requester->uid, $user->uid)))) {
		      drupal_set_message(user_relationships_get_message('too_many_relationships'), 'error');
		      drupal_goto();
		    }
		  }
		  else {
		    drupal_set_message(user_relationships_get_message('not_accepting_requests'));
		    drupal_goto();
		  }	        	          

		  $relationship_type  = user_relationships_type_load(array('rtid' => $rtid));		
		  $relationship = user_relationships_request_relationship($user->uid, $requestee_id, $relationship_type);
		
		  if ($relationship === FALSE) {
		    drupal_set_message(user_relationships_get_message('unknown_error', $relationship));
		  }
		
		  $relationship->requester = $requester;
		  $relationship->requestee = $requestee;
		  $relationship->type = $relationship_type;
		
		  drupal_set_message(user_relationships_get_message(($relationship->approved ? 'pre_approved' : 'submitted'), $relationship));
		
		  drupal_goto(drupal_get_path_alias('user/'.$form_values['requestee']));	    
	    }  
    else {
      $form = confirm_form(
        $form,
        t('How do you relate to %name?', array('%name' => $requestee->name)),
        "user/$requestee->uid",
        '',
        t('Create'), t('Cancel'),
        'user_relationships_request_confirm'
      );

      return $form;
    }

  drupal_goto();
