OMG, pity MM...

As for his habbits:

1. 他每天早上会在被子里面打若干雷一样很响的屁，吓我一跳不说，听了格外刺耳，
我说他怎么不注意一下或者预先通告，他反而说我的响屁都是不臭的。

Let it go...

2. 大声的吐痰，从来不关门地拉尿，冲厕所，因为厕所是在睡房里面，有时候我在书
桌边上干事情或者打电话恶心不说，还怕电话里面别人听到尴尬不已。拉尿手也不扶一
下弟弟，撒到到处都是，每次我都看到黄色的液滴溅在马桶边上到处都是，看到非常不
舒服，每次都是我看到了忍着恶心擦掉，讲了好多次都不听。

Don't clean after him.  Put paper towel in his hands and watch him wipe it off.  If he doesn't do it, kick him out.

3. 吃饭的时候张开口大声地打嗝，大声地吃菜，喝汤，讲了好多次同样不听，不改。

Must correct this.  Bad table manners is absolutely unacceptable.  He will be an embarrassment to you.

4. 不管家里地板干不干净，东西随地放，随时打赤脚，在地上踩完再直接踩到床上或
者放进被子里面睡觉。讲过N次要他穿拖鞋，照样打赤脚走来走去。

Must correct this.  Don't let him get in bed unless he wears slippers.

5. 眼屎经常性地挂在眼角，特别是在洗澡，洗脸后！

Remind him to wipe his eyes. But let it go if he resists.

6. 睡在床上总是拿纸巾擦有自仓（同音）屁股，然后将纸巾直接扔在地板上，第二天
起床好久以后那些纸巾还在那里，肯定是我去捡起来丢掉。

Must correct this.  No compromises.  If he can't do it, then kick him out, or you move out.

对不住大家，污染了你们的眼睛，反正这些事让我很不舒服，甚至有些恶心，难道成为
男女朋友以后，不再需要神秘感？不再需要含蓄的美感？？？非要不遮掩的让丑陋的一
切一览无遗！或者大家的LG, BF所有的男人都是如此的污浊，是我太挑剔？太洁癖？

You are not 太挑剔？太洁癖.  Maybe long-term couples do not need 神秘感, but personal hygiene is a must.
