I would like some advice on my relationship with DP, we have been together 5 years now, lived together for 3.5 years and have a 2 year old DS. I work full time and she has taken a career break to be a SAHM and carer to DS who has had health problems (which has caused no end of stress), however fortunately things are looking up in that respect. I try to help out however I can during the evenings and weekends with both the childcare and household chores such as cleaning/cooking etc to ensure that she isn't doing everything.
Obviously as a result of the difficult 2 years we have endured our relationship has been put on the back burner to some extent and we have struggled to maintain the intimacy we once had. I try to show my affection to her on a regular basis (kisses, hugs, attempting to hold hands etc) however this is not always reciprocated which leaves me feeling rejected and often lonely. She as recently said that i'm not doing anything wrong but i'm not doing anything right either. Quite frankly I dont understand and I'm not entirely sure what is meant by that as I do put alot of hard work and effort into things at home and into doing nice things for DS and her. The only thing I can think of is sometimes she thinks I am in a bad mood about something which can cause us to fall out as I will deny there is anything wrong (usually there isn't) and she then thinks I am being dishonest. I can understand how this could appear unattractive and maybe make her not want to be affectionate towards me.
Basically what I want to know is what she means by this and things I can do to improve our relationship. I can't imagine my life without her or my son and I would do anything to improve things. I was planning to ask her to marry me later this year however I am also concerned that this might not be what she wants anymore (even though she still does mention 'our wedding') and I don't want to propose if things aren't right between us
Thanks in advance for any replies
