Hi, I have a friend who I adore, we've been friends for about 15 years and have been through so much together. I've always been there for her no matter what she's going through, and she's been through a lot. I have to admit we've drifted apart slightly over the years through us both having children but kept in contact and when we've met up had a great time. 5 months ago she split from her partner who she has a child with. I often offer to meet her for a drink and a chat , message her to see how she is. But when I ask her out for dinner, drinks on WhatsApp I see she's read the message but then it takes her about a week to get back to me with an excuse not to come. Sometimes it's on the date that I've arranged to see her. I feel as though she reads the message then takes her time to think of an excuse not to see me. Shall I continue to reach our to her or leave it now for her to contact me?
