Hi @Daydream
Welcome to the Forum - I am sorry about the circumstances that have brought you here - I already know how hard this is for you though I can't possibly know how you are feeling - we all take things differently
So we have to think about what your partner needs and what you need and both are valid and necessary - very important
Your partner needs help through his loss - I don't know the details of your brother-in-law's suicide - how it happened - did your partner find him? Details really but they are things your partner is working through right now and guilt comes with suicides - I have been through this and it's important to keep some contact with your partner to ask RUOK because he might need some professional help.
But this is hard for you too - you are suffering grief yourself - I remember when my husband-to-be lost his father so long ago now - I was so young myself - I didn't know how to deal with what was happening to him and his family - you must be going through that now
You need to start by caring for yourself - this is something you have control over as you go through an uncontrollable situation. Try and eat properly and get some rest yourself and get some help with your loneliness - you need grief councelling too because you have suffered a loss even if it may be temporary - you need your partner and he has checked out for now -
I can suggest a Help Line - that is Grief Line - the phone number is 1300 845 745 and there is an on-line service http://griefline.org.au. The phone number in Victoria used to be different but if you access the website you are sure to find that. The phone lines are open from noon to 3.00 am 7 days a week
I know this is a very vulnerable time for you and your partner - I have had two suicides in my family and know how devastating this is and how both of you need whatever help you can get
And I am glad you have reached out this evening - that is not easy to do but Grief Line can help you and your partner - you are grieving too
Sending understand and love
